I have the following guns chambered in 50 AE: DE,6"; FA355,4"; FA355,7"; BFR,6"; AMT MkV; T/C Encore,10". I have fired them extensively over the years and have used the cartridge on game: ground squirrels, rabbits, antelope, deer, 1 elk. Excellent results on all, generally 1 shot kills (I know a 300 to 350 gr. bullet on a ground squirrel is a bit much!). Initially had bullet jump on heavy loads; however, reducing the expander ball to 0.496" - 0.497" solved the problem for both cast and jacketed projectiles.
