[QUOTE="SMK1000plus, post: 1618263, member: 93846"] I have more than several M70 Winchesters in belted magnums and even more Remington 700 belted magnums. Some still have factory barrels on them. .010" to .014" brass length growth is common in factory belted magnum chambers. Once new brass is fired in one of these rifles it is placed in a cartridge case with load information and that rifle's serial number recorded on it. That brass will then be used for load development and/or use only in that rifle, for the life of the brass. I have one Winchester M70 7mm Rem Mag Classic that new brass grows .023" on first firing! No matter what bullet/powder/primer/charge weight/bullet jump/etc. I tried, I could never get down to 1-1/4 MOA accuracy with that rifle, which is my absolute minimum acceptable accuracy in a factory barrel. It will soon wear a Bartlein 26" .338 cal. 1 in 9" twist Sendaro contour SS barrel chambered in .338 Win Mag. :D [/QUOTE]
