Bought a Jebs .655 for the Beretta and wasn't able to turn the patterns I was looking for with Hevi 13 6's, 7's, magblends, Fed HW 7's, etc. Spoke to Jebs and they have fantastic service dept. Going to shoot the .650 and .660 and see if any of those work. I was getting allot of gaps in my pattern and really low numbers for the shells I was shooting. Looking for a good 12"-15" pattern without allot of gaps. My thinking is that with the gaps in the patterns I am overchoked but the guy at Jebs shoots .650 with Hevi 7's. I guess I am just going to have to shoot them and see what works best. All of these guns can pattern a little different even with the same shell and choke.
