Try a big dose of reality and shoot the largest caliber for DG that you can get along with...

For me, after many years of shooting big bore rifles, that is a 404, 416 or a down loaded .470 with a 500 gr. bullet at about 2000 to 2100...and lately I have been shooting the full house .470 with a 500 gr. at 2245 FPS, but I can handle any of them if I "have to", but damn that bitch kicks.....

And never underestimate the fine old 375 H&H, it WILL get the job done....
