6 UM Reloading Thread

[PathFinder]

Interesting. I was at about 100rds. 63.5 was 3301 on my pressure ladder and created one and done brass, could’ve pushed the primer in with my thumb darn near, very heavy ejector mark. I’ll be curious to see what you end up with. Maybe +P would work well if your intention is to run h1000?

After owning a +P barrel and hearing about Ryan's, I would never do it to another 6 UM.
With H1000, I think it's a matter of trading some velocity for barrel life. Just a question of how much of each.

Ended up tweaking my original load after all my brass was fired and the barrel was fully broken in. 130 rounds down the pipe thus far. Repeatable 3-shot groups at .4” and 5-shot groups at .7”

-6UM-30
-24” benchmark 7 twist
-64.5g N570 with zero pressure signs
-115 deep cut coated DTACS
-once fired adg brass
-30 thou from the lands
-Fed 215M
-.003 neck tension (.271 bushing/ .241 mandrel)
-3340FPS, with ES of 15 with 15 shots in the chrono




I hope the primer pockets last. No ejector marks, bolt had an easy lift….hoping to have this brass last the life of the barrel. We’ll see.
