Regarding handloads for .308, I typically use the same powder charge you described or something similar to push a 168 grain HPBT match bullet to 2600-2650 fps. IMR 4064 and Winchester 748 also work pretty well for this application.
I finally figured out the Black Hills Match uses 46.5 gr BL(C) and it shoots light out in three separate rifles - far better than Federal match 168's. Nosler Ballistic tips, Accubond and Sierra Matchking all keep me under .6 MOA for 5 shot groups in an M-1 (7.62x51 Navy version), M-1A1 and AR-10
Hello Colin1,
Handloading is the process by which the spent cartridge cases are resized back to original (we hope) dimensions and the expended primer, powder, and bullet replaced with new components. It is less expensive than new ammunition and hopefully the quality is better as well. The cartridge case is the most expensive part of small arms ammunition (usually) and it is reuseable to some extent.
