[QUOTE="Michael O'Connor, post: 1632703, member: 103722"] I forget the name of the gun manufacturer that Bushmaster bought out. They had just about every magnum cartridge available in an AR frame. They had too many warranty claims and bailed out. Not all cases are meant to be used in a Semi-Automatic rifle, especially if they don't cycle well or have an inferior design. Look at how many Magnum cartridges Bushmaster has in their sales arsenal now ? I rest my testimony. If I were to build an AR-10 derivative in a Magnum frame. The only two cases I would use would be SAUM based SST (Sherman Short Tactical) or a Blaser 7mm Magnum case. Both cases will cover the realm of short and standard long action AR- style rifles respectively, with long high B.C. bullets. I will say one good thing about the .270 Berger EOL 170 grain hunting bullet, it has an optimum bearing surface length, but it still will not outperform a 7mm Berger 180 grain Hybrid, and the 270 EOL needs a custom twist barrel. Good luck, Sir. [/QUOTE]
