[QUOTE="Lenny Foffa, post: 2841653, member: 100742"] For me it would be the .270 Win with a longer throat, to accommodate 150 grn and 170 Grn. Bullets seated well out to the lands and groves. I think this imaginary change would allow for 60.0 to 61.0 grns of H4831 SC to increase the velocity to 3000 to 3100 fps with a 150 Grn Bullet. The bullet is only captured by the neck and does not enter into the case at all. Yes It would become a single shot rifle. Its what I did in a heavy custom Rifle, chambered in .270 Win with a fast twist Hart barrel 30 inches long. I [I]think this modified .270 would be able to compete with the 6.5 Creed and 6.5 PRC at a 1000 1200 Yards[/I] [I]Targets [/I]and still be able to have enough energy to take Mule deer /Antelope at 600 yards or beyond, if the shooter was able. I think the High G-1 BC of the 150 Grn ABLR or the 170 Grn Berger, would benefit from the additional velocity, in a faster twist barrel, this would generate. I have only a starting load , that was a conservative guess, when this first test was done 4 summers ago. the 300 yard Groupe with 150 Grn ABLR 1.1 inch . due to heavy barrel. I get this extra Long 270 Win was silly idea, it was just for fun!! and it WAS fun to shoot. [/QUOTE]
