I have just reloaded a few .270 cases to where the bullets are .020" off the lands. The loaded cartridges fit fine in the rifle and the bolt closes with no problems. Interestingly, I had an old un-shot box cartridge lying around. The bullet in the cartridge seemed to be seated a lot farther into the case than was the just-reloaded bullet (130 grain Nosler). I compared the two cartridges with a Stoney gauge and found that there was over a .200" leade with the factory round in the Remington Mountain Rifle. Can't be erosion, since the gun has had perhaps only 50 rounds shot through it. So, is a leade of more than a fifth of an inch customary for Remington and/or other non-custom rifles in the larger calibers, or is mine just abnormally long-throated? I called Remington and they didn't give me a good answer, asking me to send them the rifle and the cartridges so as to better clarify things. I haven't shot any of the new reloads and wonder if there will be pressure problems. I mean, a .200" difference in leade measurements has me wondering if I should set the bullets back more or leave them at .020" off the lands. I usually set the bullets back .010" for the very accurate varmint rifles, then play with that value to fine tune for accuracy. Any ideas?
