I am at 63.5. Close enough.

I tagged in and have been chasing .75-.4's with H-4350. 163HHT's Just not consistent accuracy. I gave it a quick clean after 60 rounds and switched powder to Superformance and second load was .535. I think I may be onto something. More to come tomorrow hopefully...
What projectile?

If you're not at max load for this recipe, you may want to test just a touch more powder (like 0.2g) as that vertical stringing is often a sign of just being on the low edge of your powder charge accuracy node.

I shoot 7828 ssc in a 9 twist with 212's in a 24" barrel at 2820 and it's not a hot load. It shoots 1/4 moa to 400.

you could try a little more neck tension
Good idea. I usually start at .002 but that might be just the ticket.

Thanks. I'm up near Waynesville. We do shot at Carolina west in Nebo about once a month.
How does the velocity compare with H4350 and RL17? I'm shooting a 20" and want to keep all the speed I can with a 180
