I think I made this spreadsheet several years ago. If I didn't, I stole it from somebody.
Regardless, it helps me know that the differences between different trap loads aren't as important to me as I thought.

Useless. You assumed constant velocity over distance and did not account for trans-sonic effects. Lol.

I agree. This chart fails in many aspects. I still like it.
I'm more of a relativist than an authoritarian absolutist.

I think it affirms the fact the target cannot outrun the shot charge, even with the slowest under 1000 FPS at the muzzle.

Is this chart taking into effect that the shot is slowing as soon as it leaves the muzzle? The velocity of a shotshell is not linear from muzzle to target.

No.

It describes something to me - while there are certainly numerical differences between a shell that delivers 980 fps at the muzzle and one that sends the shot at 1200 fps, the differences aren't something I can correct for. Maybe the best shooters know how to respond to minuscule differences, I can't. I showed myself that I should be able to do just fine using slower (less painful) shells.

You're right, in that a slow shell will break a target. That's your choice to shoot however slow a shell you choose. Also know that from the tests that I have seen, a shotshell will loose roughly half of it's muzzle velocity in 50 yards. No matter how fast it started or the shot size. Therefore the data in your sheet is incorrect. This test is on everyone's favorite shotgunner's website, Randy Wakeman. Although the test was done by Ed Lowry.

No. From a learning to shoot trap standpoint and all that goes into that, what happens from the time the gun goes bang and the target breaks or doesn't break is of little use to me at this point. Maybe if I was running 98-99 straight on every outing I might put some thought into this.

Diesel, can you provide a link to which of the 100’s of articles on the Waksman site has this table. Thanks

TOOOO much math....Not enough targets broken.
Be man enough to know you missed.
figure out the WHY not the WHERE
and always think BREAK THIS ONE !!!
