RE: nitro loads?
If you are worried about the 7's being to small, have Ray to load you a few 5's or 6's, I have been using his Hevi-shot #5's the last couple of years and they are awesome. I just patterened my BPS a couple of weeks ago, At 46 yards I had 240 pellets in a 12"X19" turkey target and they were straight #5 shot. Nitro and Rhino has something figured out that no one else has when it comes to a great pattern IMO.
