What does this two shell pattern at at 25 yards say about "full" choked barrel on early 12 ga. field grade Winchester Model 21
One inch circle is point of aim

It would be shooting too high for me, but that can be corrected. Other than that, fine looking patterns. I assume that's 7 1/2s or 8s.

Is that two shells out of the same barrel, or did you mean that it is one shell out of each barrel and they both are choked full? If the latter, it looks to be excellent regulation, too.

I wouldn't consider those "Full" patterns.
Even with soft shot, set back deformation, and OTC speeds, it looks too wide for me.

I get shredded paper plates at 40 with "Full".

But I'm no M21 guy either.

It definitely shoots quite high.

You'd have to shoot 2' or more below decoying ducks.


Out there doing it best I can.

The barrel expert, Ken Eyster believed a 5-shot group best to establish POI. With only 2 shots you could easily flinch on one of them and data would then not be reliable. Less experimental error with 5 shots. Also, a single shot would be best for a study of pattern density.

a faster load leaves the barrel b4 recoil raises the barrel causing the gun to throw the pattern higher....

Why don't you check it at the standard 40 yards?

What if the faster load has more recoil; as it will if the shot load is the same? DDA
