I too have a 6mm Remington. Actually, it is a .244 Remington in one of the original Remington M722 short bolt actions. Being a .244 and not a 6mm Remington, (they actually are the same cartridge and are interchangeable) my rifle has a 1 in 12 rifiling twist which will not stablize the longer 100 grain spitzer bullets. When the cartridge was brought out the second time in the 6mm Remington, the guns were given a 1 in 9 twist which would stabilize the 100 grain bullet. However, the .244 will stabilize the 90 grain bullet which is just as affective on deer as the 100 grain. Being a reloader, I prefer the 6mm Remington over the .243 Winchester because of the longer neck and the slightly greater powder capasity. You can't find a better varmint cartridge and it is no slouch on deer either. You have one heck of a nice rifle. The down side is the expense and availability of ammo. Might be a good time to start reloading.
