Re: Case length and OACL
The dimensions I am referring to are those given in the Hornady reloading manuel, 7th edition. My OACL is the same as C.O.L. and I understand that it is actually different for many cases.
I understand the relationship of the base of the bolt to the chamber depth and I thought it "could be" hurting my accuracy to seat the bullet .075 deeper into the case, to accomodate the canelure, thus moving it at least that much further from the rifleing lands.
Is it common for the COL stated in the reloading manuels to create such a difference in the distance from the mouth of the case to the center of the canelure?
