In this video I'm trying to find the optimal cartridge over all length. I started with the bullet seated 20 thousands off the lands and backed off 2 to 3 thousands after each set of 5 rounds. I'm attempting to shoot groups of 5 to find the smallest group of groups. Brass used is Hornady, large rifle primer, powder is Hodgdon Superformance, and bullet is Hornady 143gr ELD-X.  Use code KYTAC for 10% off your next purchase at Burn Proof Gear Thanks for watching, please like and SUBSCRIBE.
