Until very recently that's all I shot except for games. Now I've gone to a fast (1390) 7/8 of 7 1/2's and through a mod choke they crush targets way out there. You get a few less pellets with 7 1/2 but they retain energy better.
17.8 Red Dot 1oz 7 1/2 .025 16 to 27 and shot a 27 wobble last week with the same load. Good results registered 16 yds. 1 oz 8's on first shot of doubles and 1 oz 7.5 on second. Have mixed them with nearly the same results in practice. Shoots good and saves a few $
I use Green Dot or Tightwad powder, 1 oz. 7 1/2 magnum shot. I load to 1250 fps. I struggle with targets beyond 60 yds but I believe this is shooter error. This speed breaks targets well and recoil isn't bad.
