That is pretty much the same recipe I use except I use Federal primers. I'm dropping 15.9 grains of 700X and I think when we chronoed them, they were between 1200 and 1250 fps.

 

Suggest you contact Claybuster through their website contact info Claybuster Wads
Ive used 8 lbs of 700x loading 17gr or a tad more with what youre wanting to use. Also, is the AA the HS or CF hull? If I remember, the HS hull lacks interior room, you may need a shorter wad. I keep a supply of CB 1oz wads for those tapered hulls that need a shorter stack height, depending on the powder density.

 

16.5 to 17grs 700x with a CB0178 wad in a Gun club or AA CF hull with a Federal 209a primer and 8.5 Magnum shot.

 

I load AA's with 14.9gr. of 700x, W209 primer, #8,8.5 or 9 West Coast shot, and CB1078-12 gray wads for skeet. (actual gr. on scale is 14.6-14.7) Perfect crimps and no problem breaking targets. (mec bushing #25, on a 600 jr.)

 

I'm not sure why, but Hodgdon does not list any loading data for 7/8th oz loads
using 700x. They have data for 1 1/8th, 1oz, 24gram & 3/4 oz but no 7/8ths.
Go Figure,

Use 24 gram data. Close enough to 7/8ths.

 

16.3 grains of 700x, clay buster wads in AA’s work well for me.

At 14.9 what is the velocity?

 

I don't own a chronograph so I really don't know.

Mach1,
What does the loading data for this load claim the speed & pressure to be?
I can't find this load listed anywhere and I have quite the collection of load data not excluding the mfg. online data.
Thanx,
MG

 

I with mg1polo on this I have used 700X since I was 12 and that load is just not what 700x is for, when you use that little of powder 700x just doesn't burn right. just use the right powder for that light of load. I use International for my 24gram 700x for 1oz and 1 1/8 oz, blue dot for 1 1/4oz or more

 

In 24 g there are 0.84657509 oz. I have been told by Hodgdon that it is safe to use the 24 gram data for 7/8ths. The 24 gram data also looks very much like the 1 oz data for safe powder drop range.

 

I loaded your receipt once with the exception of the primer. I used Federal primers, AA's, and 15 grs of 700X.. On a nice day I recall breaking 25 straight on the 27 with that load. I only loaded those once just to see what they would do. I think I still have the remainer of the wads. Very light recoil, and they did break targets.

 

With the standard unaltered Mec 7/80z bar you're only getting 24grams or less so there is no pressure problems.

 

Hello All, this is my 1st post,altho I've been reading posts for a while. My question is what gun are you shooting this load out of. I like 3/4 oz 12 ga loads, I primarily shoot skeet but my Load is either GC or AA hull, Winchester primer, 16 grains of 700x & a claybuster 0175-12 wad. The reloading data comes on the paperwork that comes in the bag. The loads work fine in my O/U but most times won't cycle my Beretta 391 Teknys. Slowly raising grains to get desired results. Latest load is 18.8 grain, everything else stays the same. Going to try load today before the snow. Any suggestions ? Been using 700x for a while. After I use the new 8 pounder will look for something else to use. Thanks

 

WOA there Mario,
At 18 grains your already passed the MAX for 700X using Remington Hulls.
Your speed is already passed 1325 fps.
Where are you coming up with 18.8?
That's Insane!
MG

 

I don' like 700X. Here is a load from Lyman's 5th. SS/CG hull, STS209P, 18.5gr 700x, Fed 12S0, 7/8 oz for 1310fps @ 9500psi. They list no load for 700X under 1300fps, so I'd use a different powder..

 

Here in lies the problem.
Mario is using Winchester Primers.
That load only exists with Remington hulls with a 17 gr MAX.
There are NO 700x loads listed by Claybuster 0175-12 with 700X period.
Going to 18.8 gr for the sake of getting his gun to eject is flat out STUPID!
MG

 

So mg1polo your wrong! Received these wads back in Nov. On the Brochure that comes in the bag of CB0175-12 are listed 73 different loads, 16 of them are for Remington, CG, Nitro, ect. using 700x, 4 of them call for Winchester Primers, 13.7 gr, 14.8 gr, 16 gr & 17 gr. Don't know how to upload this brochure but it is listed on the claybuster web site. I see no problem using the data in the 2018 Hodgdon brochure, 24 gm data but using about 1/8 oz less shot. Load: 24 gm,CG/Rem. hull, Win 209, 3/4 clone, 18.5 gr, 9700psi. Looked at Claybuster info, Lymans & Hodgson. Pressures all over the place

 

I am looking for recommendations for another powder for 3/4 loads, Clays ? American Select?

 

American Select is a good one.

 

The 3/4 oz 700X data from Hodgdon is much different than the 24 gram data. With 3/4 oz., I would say 18.8 gr. will put the load overpressure. With 3/4 oz and 700X, pressure seems to build quickly. I agree with mg1polo that increasing the powder charge of a load in order to get your autoloader to cycle is not a safe practice It likely is difficult if not impossible to get most autoloaders to cycle 3/4 loads with proper loads, the loads are too light. Here are both:

 

24 Grams =.846 of an oz. ---- 7/8 oz. =.875 grams ---- That's pretty darned close. Unless you are working at absolute max press. I wouldn't think 0.029 of a gram would make any measurable difference. You couldn't even measure that unless you used an electronic sale !

So, I'll say it again, where do you see 18.8?
You go right ahead and doubt the powder mfg's data, that's your business. I'll continue to trust those that mfg. the powder.
Go to the Hodgdon website and see for yourself.

I load extralite and have been very happy with the loads. 15.7 grain gc hull cheddite primer and cb0175 wad. Probably about 1200 FPS. Maybe a little faster. Works well for me.
