Sierra Heavy TMK 6MM Testing

Does it come up to the base of the shoulder? IIRC (probably don’t), that’s where it usually is for me

Yep, looks about there.

You guys suck (yet again). 6mm dies, 18" 1-7" Pbb .750 fluted barrel, and 116s when they drop are (or will be) ordered.

Yeah, then it’s not low enough case fill to be concerned about IMO. I’ve never had issue with angled shooting or erratic velocities or anything. But then again I don’t seat the bullet up the case neck, I want the whole neck grabbing the bullet.

I say rock on, I’ve gone through at least three jugs of H4350 in 243/6CM in the 41-41.5 range.
