I purchased a Wby sub moa MK V in 6.5 300 when they first became available. No brass of loading components at that time. So I purchased 4 boxes of 130gr sirocco's, and 4 boxes of 140gr. A-Frames. Sighted the rifle in with the A-Frames and shot an Elk in 2016 which was a bang flop at 175 ish yards. I have carried this rifle several more years and killed a Mule Deer with it two years ago. I check and verify the zero each year and I don't shoot it between hunting seasons. I will when I run out of factory ammo. Rifle still has less than 40 rounds fired through it. Barrel life will be the same as the 26 Nosler as they are very close to each other in velocity. With Wby's long freebore it will probably last longer then the Nosler that has a shorter throat.
