I just went out today and checked the pattern on my shotgun.

My set-up is as follows-
Mossberg 500 12 guage w/ 28" ported barrel, white front bead, gold rear bead.

I have a Carlson's extended choke Hevi shot full, .700"

I am shooting Winchester Supreme High Velocity Turkey loads. 3" 1/ 3/4 oz #5's.

I first checked the pattern at 20 yards (approximately), and then moved to 40 yds (approximately).

The 20 yard pattern was centered just low of my aiming point.

I was using butcher paper for the pattern.

I then moved to 40 yards and used a single sheet of butcher paper also. There were surely some off the paper at 40 yards, but I don't know how much, though after shooting at 20 yards, I am pretty certain the load was centered left to right on the paper.

I counted 121 hits at 20 yards, and 44 hits at 40 yards within a 10" ciricle which I figured to be close to the average center of the total pattern.

Is this acceptable, or do I need to work with a different load?

Here are a couple pics.

Thanks,
