[QUOTE="Scott E Ames, post: 2545819, member: 60439"] Do you mean 3900 fps or more likely 2900 fps? I have a full custom 45 SML and using IMR 4198 I got to 3000 fps and my magnum priming modules expanded enough that they got tight in the shell holder for de-priming. I spoke to the gunsmith that built my rifle and he said that is similar to getting case head expansion on a centerfire and I was over pressure and should back off. I decreased my charge to a 2750 fps load with the 300 gr. .45 cal. Pittmans and got this 3 shot 100 yard group. [ATTACH alt="SML, 45 cal..jpg"]370233[/ATTACH] The recoil at 3000 fps was more than my 416 Rigby. The 2750 fps loads are pretty pleasant to shoot. I would feel comfortable to 400 yards with my system but ballistics and time of flight get pretty challenging after that. If you really are getting 3900 fps what powder/primer are you using? My rifle is a Jon Beanland custom 700 magnum action Bartlein 26" barrel (Heavy Palma contour) Macmillan ADL stock Triggertech trigger Huge muzzle brake (brand?) This system certainly out performs a 375 H&H but I think a 338 Lapua would be hard to top, especially at a longer distance. [/QUOTE]
