6.5 PRC using Accurate MagPRO Powder

[Farmboy491]

Reloading data for the 6.5 PRC has been hit or miss with any given powder / bullet combination. I was looking for load data to use with Accurate MagPro powder and the 156 Grain Berger ELO Elite Hunters and really couldn't find any data. Accurates website load data stopped at 147 grain bullets. I used their load data to plot start / max loads versus bullet weight and came up with a good correlation to start my loads. Of course, start low, work up. I wound up landing on 57 grains Mag Pro, 156 Berger ELO, 2.308 CBO (to fit my Magazine), CCI 34, Nosler Brass Trim 2.023 and Magnetospeed 2860 fps. Browning X-Bolt Stalker 26” Barrel I’m currently breaking in and it is still speeding up. 0.5 MOA at 100 yds. Should break the 2900 fps benchmark as it loosens up. I may need to adjust powder again a little to tweak accuracy as barrel peaks. Just thought this info might help someone else.

Barrel Break-In Chrono Data using 67 Grains US869 and 140 Grain Hornady SST bullets. US869 was all I had when I got my gun. These were slightly compressed loads. US869 is definately a slow crawler, but I can see my ES dropping and my MV creeping up as new barrel breaks in. Was getting 0.7 MOA on last groups and averaging around 2800 fps out of 26" barrel.
