I have 3 6BRs, all 3 prefer H335. Proffered pill is 90 or 105 Lapua Scenar.
That's another powder I never would have thought of......
Lee hand press; msrp is $65...
Clumsy but works well!

Just curious....are you running a .236 or a .237 bore?
I know it's .275 neck and .134 freebore.........
Not sure what the bore was on this one.

Randy, I have Berger 95 & 105 VLD's and a pound of H335.....mind if I ask where you got your data for H335 or what you're load is for the 105's?
Not great results........The first target is the 30 grain load with a .006 jam at top (the off one was me) and the bottom was a .003 jump that shot so well before. Didn't do so well today. Remainder of the groups are the 30.8 load staring with a .006 jam and going to .009 jump.
On another note, I'm tickled with my 300 PRC and 215 Hybrids over 79.5 - 80.5 grains of N570!

Groups at 200 yards on the 6BR?
Yes. The top row.

Next I would stay with .006 in the lands and tune the vertical out with the powder. 30.1, 30.2, 30.3, 30.4 & 30.5 and see what happens. I'll make a wild *** guess that .2-.3 tenths should help it. But of course, I've never done this before.
Thank you for the help! I like the .006 jam but a little leery of a jam for a PRS gun.........Next I would stay with .006 in the lands and tune the vertical out with the powder. 30.1, 30.2, 30.3, 30.4 & 30.5 and see what happens.

.006 isn't really that much. Load a couple of dummy rounds, and after the rifle is dirty, chamber and extract them a few times to see if the bullet moves. Take some measurements before and after each time. I don't think you'll have a problem, but you never know. How much neck tension do you have? And you're welcome.
