We patterned our guns...

[Lonster]

I called Rob Roberts at Gobbler Guns on Tuesday morning. He is a super nice guy and we talked for over thirty minutes about turkey guns/chokes. He is THE man when it comes to Benelli turkey guns (he does Benelli's custom turkey guns). I ordered Mrs. Lonster a choke for her new M2 20 gauge and ordered me a choke for my SBEII.
I was quite surprised when they arrived at lunch today. We are going to shoot them this afternoon and I will follow up with our results.

Shots were at 40 yards (used a rangefinder).

M2 24" barrel
RR .560
Federal HW 3" #7's
10" paper plate
102 pellets


SBEII. 24" barrel
RR .655
Heavy Mag Blend 3.5". #5,6,7
129 pellets

Win LB 3.5". #6
197 pellet

Were your shots centered on the plates?  Your numbers seem a bit low.  I would suggest using large paper, then cover the most dense part of the pattern with the plate and adjust poa/poi accordingly.

If you want good numbers with the Federal Heviweight #7 shot. Try a True lock choke built for that shot. My 3" gun will do 180 in a 10 at 40 all day. That Heviweight shot is nasty stuff.

And if you want to shoot the Hevi shot mag blends I have great results with a .660 rhino, my 3" gun will do 220 in the 10 at 40.

Those numbers are LOW.  My SBE II with a Pure Gold .670 and 3.5" mag blends breaks 200 @ 40 yards with boring monotony and 250 with 3.5/2.25/7 hevi.

You should be able to also get 130-150 with the 20 depending on whether the gun likes to shoot dirty or clean.

Ok guys I shot a much larger target and moved my sights so that my pattern was in the center of the target. 2 shots with the SBEII, 40 yards, 10" = 211 pellets and 210 pellets with the 3.5" Magblend 5,6,7

I can live with this.

Good deal,  with the 3.5 shells you should be doing better than the numbers you are getting.

[FullChoke]

That is much more like the numbers those shells are capable of laying down.

Good to go.

Those are great numbers.  A good even pattern is what you're looking for.  Great job!

[albrubacker]

That should do the trick!

Those numbers are terrible.  Box those guns up and send them to me and I will get rid of them for you.
