Thanks woolleyworm
The Rem 760 that fired inadvertently, as mentioned above, would come in at 80.6 mm or 3.17" of COAL!! So I was sizing down ammo to fit this gun, and sizing up ammo, to fit the Rem 700, 30-06.
I hate to have two different sizes of ammo, but can't seem to get around w/o selling my "possessed gun".
As for the Rem 700, (longer than spec COAL gun), the problem arises when the bullet protrudes to far out the neck, (maybe???)
That is why I thought to seat the bullet in the neck at least .308", (that's what I recently read somewhere).
I mean, if the bullet is only seated in the neck 1-2mm, I assume this could cause problems?
So, the 760 is off to a gunsmith, and the 700 is operating fine with long COAL's issues. I am using IMR4350 at 55 grains, 2275C Sierra Bullets, .308.
I have 200 rounds with powder but have not seated the bullets yet.
Thanks for your advise, I should be paying ya all.
