[QUOTE="Topshot, post: 1027095, member: 13285"] Not sure what to make of this little project of mine. A silly little idea seems to have taken on a life of its own and I ended up with this thing on the left with a .338 RUM on the right for comparison. [IMG]http://www.austargets.com/imgs/gibbs510a.jpg[/IMG] It is a .510/505 Gibbs (.510 Beecher) with extended throat to maximise case capacity. Holds 179gn H2O to level with the case mouth. The Bullet that I will be using will be the 750gn Hornady A-max. I have the barrel, brake, reamer, brass etc ready and will have it all put together over the holiday period. The brass is high pressure Bertram brass designed to run at Cheytac cartridge pressures. For a launch platform, I will remove the barrel off my .375 Cheytac. It has a 408 Stiller single shot action so should be good for 65kpsi No idea what load to use but hope to live to tell about it. :) [/QUOTE]
