I'm new to this forum and relatively new to reloading (<2 years) and I'm not sure if this question has come up or not so here is my situation:
(Please know that I understand the laws and dangers regarding ap bullets/ammo. I am strictly concerned only with load data and information regarding reloading these bullets.)
I have obtained some 164 grain .30 caliber armor piercing bullets (black tip) that appear to have been pulled from military surplus ammunition. My speculation is that they came from .30-06 ammunition. My concern is that I want to load them in a .308 Remington 700. The twist is 1:12 and I typically reload 168 gr Sierra HPBT with 44 grains of Hodgdon 8208 xbr in Lapua brass. However, when the 2 aforementioned bullets are compared side by side, the ap ammo is noticably longer. The difference is 0.205 in. I'm a little concerned to use the listed 165 grain load data on a bullet that is so much longer as this will affect pressure, right?
Here are my questions:
1.)Is it possible to reload these bullets for .308?
2.)If it is possible will my twist rate stabilize a bullet of this length since it is close to a 180 grain bullet length?
3.)Should I use 165 grain load data for reloading .308? Or should I use 180 grain load data since the bullet is going to be deeper inside the case?
I appreciate any information. Thanks.
