Ya Ernie, I get well over 1800 FPS. with the 240 grain XTP mag! 1889fps. average to be exact. The 200 grain FTX which is a much thicker jacket than the 240, and gets 2000+ in my 7 1/2", I have to pull the flex tip out of the nose to get them to fit in the cylinder when crimped in the deepest crimp groove, (there are two grooves), but I have talked to the Hornady tech's and this is the heaviest constructed 200 grain they make except for the solids, and I assure you it will smoke a deer! but the best big game bullet is my hard cast 340 WFNGC and it will do nearly 1700 FPS. (over 1650)I aint going to Africa but I think the 454 would work, anything in the lower 48 is just novelty if you use more, heck, I don't need any more than my Colt with the 340 and it will take anything in the lower 48 with athority! But in my opinion the 454 has an edge on the 480 and real close to the 500!
