Wow, that is a gorgeous A grade!
I finally had a chance to shoot my 30" f/f choked 16 O grade today, and I'm glad I did! I was invited to shoot trap, which I hardly ever do. I put a slip on comb raiser on it, and that little gun knocked my socks off. I think I shot a 21 or 22 with it, which is good for me since I usually shoot skeet. Dead on and velvety smooth is the best way I can describe it. I had planned on selling it, but now I'm having visions of late season roosters and chukars, dropping like flies at 40+ yds... I'm surprised these SAC guns don't get more play.
