Need expert opinion on bullet Diameter
Here is the situation. I have a rifle that has a .310" dia. bore and I've been shooting .311" bullets in it with great accuracy. Around .3 MOA. I just recently found some bullets of the same style by another manufacturer only .312"
Should I be able to safely shoot a .312 bullet in a .310 bore?? Would .002" really make any difference?
I originally had no plan of changing bullets but now with the "rush" reloading stuff is getting super hard to find right now. I can't find the .311" in stock and they have the .312" bullets in stock and $10 cheaper per 100. Both bullets are HPBT 174 grn match bullets.
Side by side picture comparrison of bullets, it appears the .312" has a shorter bearing surface and a faster taper to the point and the .311 is slightly more round coming back from the point and has "guessing from pictures" maybe 1/8" or slightly less additional bearing surface.
Need some professional help here. Don't want to rip up my bore or face by trying to force a bullet through it that is too much difference.
