My understanding from the rule book this load is legal due to not being over 1290, but the 3 1/4 drams does that make it illegal. Thanks everybody

Factory or reload?

from the rule book
3. Any load with a velocity greater than 1290 FPS (Feet Per Second) with maximum shot charge of 1 1/8 ounces, or 1325 FPS with a maximum shot charge of 1 ounce, or 1350 FPS with a maximum shot charge of 7/8 ounces or less, as measured in any individual shotshell. These velocities are maximum and no individual shotshell shall exceed these limits for the designated shot charge. In addition, no load containing more than 1 1/8 ounces or any shot larger than Number 7 1/2 can be used. Shot charges are maximum and no charge may exceed the charge amount by more than 3%. Steel shot in Number 7 will be acceptable as long as velocity criteria are the same as for lead shot shells.

Not to open a can of worms but...

Nobody will challenge you with this load, if it is a factory load. They will look at the label and say, "it's under 1290 fps so it's legal."

Except, in reality, it might not be.

I'm assuming these are USA-manufactured factory shells. If so, USA cartridge manufacturers voluntarily follow SAAMI guidelines.

And since SAAMI allows a +/- 90 fps tolerance on the stated muzzle velocity on the box, it is possible that there are cartridges in that box that have a 1345 fps muzzle velocity.

But nobody is likely to challenge factory shells, and furthermore, there is nothing in the rule book that tells you how you are supposed to check the muzzle velocity of a shell if a challenge is made.

So this is a long way of saying that the shells you are using may or may not actually be legal shells, but you're safe to use them.

All that is true. So thinking along those lines, the Rem Nitro 27 that everyone speaks so highly of (and I'm not opposed to shooting a box or two myself on occasion) with a stated velocity of 1235 on the box, or the AA Super Handicap (Silver Bullets that are now grey) with a stated velocity of 1250 or the Fed Grand Handicap with the same 1250 FPS velocity, might all contain shells that are at 1325 to 1340 FPS with a 1.125 oz payload. Would be interesting to chrono a box of each of the above to see what actual velocity is for individual shells.

Now I know what some of you are going to say, but I found it is useless to argue with the ruling class of a gun club. Some clubs still have their rules prohibiting any shot shell bigger than the old 3 dram, 1-1/8, 7-1/2 shot size on their trap ranges, even though ATA no long has that rule. Why? Because it is their club, their rules, they will tell you it is a safety issue or an encroachment issue. I happen to be a member of a club that still holds on to this old rule, I am telling you fact.

So while it may be legal for ATA, make sure it is legal at the facility you are shooting the ATA event.

I have seen folks shoot these and no one bats an eye. 1&1/8 ounces of 7&1/2 @ 1275 FPS.

I have never heard of anyone challenging factory loads at an ATA shoot.
In fact I have only seen 1 or 2 challenges ever of reloads and none in the last 20 years.

Back then I think they identified the powder and weighed it and the shot.
But I am going from memory.

"Shoot Management, ATA official(s) or any contestant may challenge the load of any other contestant.
Any challenge shall be initiated so as to not disrupt the harmony of the shoot or interfere with other contestants not involved with the challenge.
On receipt of a challenge management or ATA official(s) shall obtain a shell or shells from the challenged party, and if after examination, management or ATA
official(s) find the contestant violated the ATA rule, he/she maybe disqualified.
Any such initiated challenges, determined to be abusive in nature, will be referred to the ATA Executive Committee for disciplinary action."

I feel pretty safe shooting factory loads.
I would consider challenging factory loads to be abusive in nature and push to have the issue referred to the EC.
I don't think the good folks @ Winchester or Federal would appreciate it either.
They might even question the ATA's method of testing said shell(s).
It could get litigious.

It would never get that far. The ONLY thing the ATA could possibly test is the weight of the shot charge and the size of the pellets. And even the size of the pellets is dubious since they're never perfectly spherical..

There is nothing in the ATA rule book that prescribes how one would test muzzle velocity.

I have been trying and trying to get someone in the rules committee to listen to me on this subject, but so far, it's just howling at the moon.

Also true. They follow the Chronographing standards in the SAAMI standard. (ANSI/SAAMI Z299.2, I think the current standard is 2015.) It's available on the internet if you look hard enough.

The chronographs they use (and incidentally, Neil has one) are "Induction Chronographs." Not the usual "Light Sensor" chronographs commonly used by reloaders for rifle, and sometimes shotgun.

I think the standard does allow light sensor chronographs but I am pretty sure the cartridge manufacturers all use Oehler inductive units.

What Tim said

Shotshell pressure and velocity testing 2015
https://saami.org/wp-content/uploads/2019/01/SAAMI-Z299.2-Shotshell-Approved-2015-08-31.pdf

Ammunition tested subsequent to manufacture using equipment and procedures conforming to these guidelines can be expected to produce velocities within a tolerance of ±90 fps of the tabulated values.
p. 6 All lead loads fired in 30” test barrels with a choke constriction of .031 ±.005; p. 9 non-lead .005” ±.005
p. 8 Velocity is measure at 3 feet (CIP shells are measured at 2.5 meters)
p. 84 Transducer mounting port in the receiver collar of the test barrel is at 1 inch

1) Pellet size variations allow for +/- one pellet size (+/- .010" dia.) of variation in game loads.
A No. 6 (.110") game load could contain pellets ranging in size from No. 5 (.120") down to No. 7 (.100").
On target loads it allows for +/- ½ pellet size (+/- .005" dia.) of variation; a No. 8 (.090") target load could contain pellets ranging in size from No. 7 1/2 (.095") down to No. 8 1/2 (.085").

2) Load weight variations can range from +4% to -7% in game loads and +3% to -5% in target loads; about +/- 1/8 oz. of variation allowed per shell.

3) Pellet counts per ounce can vary by +/- 10% for both game and target loads.

4) Load velocity can vary by +/- 90 fps for both game and target loads.

5) Load pressure
Maximum average pressure for 2 3/4" and 3” shotgun shells will be 11,500 PSI +/- 900 psi, with some maximum extreme variability not to exceed an uber-max of 12,500 psi +/-900 psi

6) Proof loads:
If a manufacturer uses a SAAMI proof loads, then the gun will be proofed by a lot of no less than 10 shots of ammo loaded to a maximum proof pressure of 20,500 psi +/- 900 – 4600 psi, or uber max of 25,100 PSI; and, will be similarly a MINIMUM average proof pressure of 19,000 PSI +/- 900 – 4600 psi for an absolute minimum proof of 14,400 PSI.

This is the one I always like to quote when people say "my gun likes 8's," or "my gun likes 7-1/2's"

The label might say 8's but the pellets are probably an unequal mix of 8-1/2's, 8's, and 7-1/2's!!!

It’s been nearly 100 years since smokeless powder has been commonly used in shotguns. I say it’s time to drop the dram equivalent on all shotgun shells. It confuses many shooters and has absolutely no value today. Printing the weight of the shot and velocity is the only thing that matters.

The ATA wording pertaining to velocity is also very poorly worded. With ammo varying +/- 90 FPS it’s dumb to say no shell can exceed the limit of 1290 FPS with 1 1/8oz. of shot. Many factory shells have an average of 1235 or 1250 and the reality of the entire box being over the limit is entirely possible.

Many factory shells have an average of 1235 or 1250 and the reality of the entire box being over the limit is entirely possible.
Here's what I wrote to the rules Committee:
I am an ATA life member. My State of residence is Kansas.

My rules change proposal is to eliminate the ATA rule which imposes a tiered muzzle velocity limitation on shotshell cartridges used in ATA competitions.

Specifically, the most current rule book found online at the ATA website states, under Article XIII “Standards for Traphouses, Targets, Target Setting, Guns and Ammunition” Section G, “Guns and Ammunition” Paragraph 3:

A contestant cannot use:

Any load with a velocity greater than 1290 FPS (Feet Per Second) with maximum shot charge of 1 1/8 ounces, or 1325 FPS with a maximum shot charge of 1 ounce, or 1350 FPS with a maximum shot charge of 7/8 ounces or less, as measured in any individual shotshell. These velocities are maximum and no individual shotshell shall exceed these limits for the designated shot charge.

This rule is essentially a “paper tiger” and cannot be enforced in the event of a challenge, and here’s why.

1. There is no stated rule or guideline in the ATA rule book on how shoot management is supposed to test muzzle velocity, should a competitor be suspected or accused of violating the rule.
2. Even if there was, it would be onerous on all the small clubs that throw ATA targets to have the appropriate equipment on hand to perform such a verification.
3. Testing via some outside organization that performs such testing is useless because the results wouldn’t be available until weeks after the competition.
4. In light of the above, I doubt many challenges are lodged, because even if there were, there is no way to conclusively establish whether the allegations are true or false.
5. Nearly all other sport shooting organizations (e.g. NSCA Sporting Clays, DTL, FITASC, Universal Trench Trap, NSSA Skeet, ISSF International Trap and Skeet, etc.) set a limit on shot weight and shot size, but not muzzle velocity, and it does not seem to have harmed or hampered these other disciplines.
6. Finally, and perhaps foremost, what is the point of the muzzle velocity limit? What does it really gain us?


The rule, as stated, is unenforceable, and therefore superfluous.

At present, the only thing shoot management can go by is the label on the factory shotshell box, if it even states the muzzle velocity at all. (Some still only reference drams equivalent, which brings up another entire mess because there is no absolute standard for what muzzle velocity drams equivalent corresponds to.) And even if the box does state the muzzle velocity, the standard used by US cartridge manufacturers published by the Sporting Arms and Ammunition Manufacturer’s Institute (ANSI/SAAMI Z299.2 – 2015) allows a tolerance above or below the advertised velocity on the box. So those Winchester AA gray handicap shells that say 1250 FPS on the box, any one actual cartridge, or even the entire box of cartridges may be as fast as 1340 FPS and still be within SAAMI standards, but may therefore be technically illegal for use in ATA competition as currently published within the rules.

And if the cartridges are made in a foreign country, who knows what standard they follow for muzzle velocity?


Also, many shooters reload, so there is no way for shoot management to conclusively say what the muzzle velocity of their cartridges might be. If challenged, all shoot management could do is weigh the shot and the powder. And then, even if the competitor tells shoot management what powder, primer, and wad they are using, they can only go to the powder manufacturer’s load tables to establish the muzzle velocity, and even that is dubious because the published reloading data from the powder manufacturers is not exact.

And even if there were a method of testing in the rule book, and a competitor’s shell was found to exceed the limitation, one can only say conclusively THAT shell was illegal. But what about all the other shells in his box?

I truly believe that the vast majority of ATA shooters are shooting legal cartridges within the current rule framework.

I am not lobbying for this because I want to shoot faster shells. I have no interest in punishing myself.

I do not believe that shooting cartridges with higher muzzle velocity offers any palpable competitive advantage over shooting slower cartridges.

I just believe that it is meaningless to have a rule in the rulebook that serves no real purpose, and is unenforceable.

ATA is the one and only clay target shooting organization I am aware of with a muzzle velocity limitation. Lack of a muzzle velocity limit has not had any tragic effect on any of the other clay target shooting disciplines, and I don’t believe it would significantly change anything for ATA.

If this change is made, I really don’t think most shooters will go out and buy, or reload, a bunch of shells with 1500 FPS muzzle velocity. But so what if they do?

I have debated this subject with former ATA President Neil Winston on several occasions, and we respectfully differ in our opinion.

In my opinion, the rule book must either have a precisely stated procedure for shoot management to follow in the event of a cartridge velocity challenge, or eliminate the muzzle velocity limitation in its entirety.

My recommendation to the rules committee is to leave the 1-1/8 ounce shot weight limit (including the existing 3% weight tolerance) and the number 7-1/2 pellet size limit (including the SAAMI allowable tolerance of +0.005") in place and eliminate the muzzle velocity limits altogether.

Note, there is currently no procedure in the ATA rule book on how shoot management is supposed to test the shot weight and pellet size limitations in the event of a challenge, and I would gladly offer my services to write such a procedure should the rules committee believe this is beneficial (I REALLY think the rule book needs such a procedure!)

For your consideration,

Let’s hope the ATA is actually smart enough to listen. I think if they regulated only the amount of shot and the size it would work. I can’t see where speed would matter enough to make a substantial difference. If some moron thinks 1500 FPS is better then by all means let them punish themselves and have fun. Nice letter Tim, and I’d be interested to see a response if you get one.

So I am new to the trap shooting game, 4 years now so you long time shooters could maybe tell me when was the last time that you were at a club that actually had a certified chronograph operational to test the velocity of someones shells should there be a challenge, I posed this question to one of our older shooters that has just past the 500,000 registered target maker and he said he had never seen it, my take is that if someone wants to load 3 1/4 or 3 1/2 dram 1 1/8 oz and kick the poop out of himself through 300 a day then have at it buddy, by day 2 he would probably be flinching so bad he couldn't hit the back of the trap house, not to mention black and blue

Never.

I have not asked, but I would bet there isn't even one at the Grand.

There's no such thing as a "certified chronograph." The closest would be an Oehler System 84 ($12,000 plus support equipment of similar cost or more) which had been zeroed in using SAAMI reference ammunition. It would take a year a so to put the machine together and house it, another year to learn to use it.

Trapshooters have simply no idea how different a SAAMI approved chronograph is from the one they get off the internet.

You can get very close with a consumer chronograph if you use an open choke and follow this.

Chronographing Shotguns

If you don't you will have no idea about your shot speed.

You can also look at the shellbox or reloading manual and do just fine.
