22 Creedmoor and 85.5 Berger

[Iron Worker]

On the Hodgdon website, they give some high velocity with the new Ramshot Grand powder behind a Berger 85.5 Hybrid. Has anyone tried that powder yet? It's one space slower than H1000. Maybe a Magnum primer would be needed.

Excuse my ignorance, but is it an extruded or ball powder?
No such thing is available here, but if it's ball powder, the brass is SRP, then, yes, you would want a magnum primer.
If it's extruded, even if SRP brass, then I would think a magnum primer is not required.
If brass is LRP, then no magnum primer is required either way.
I will say, I test both standard and magnum in both sizes regardless of case size….there is ALWAYS a clear winner on target.

Cheers.

Grand is a Ball powder. I think I will also try Re#26

I'm using Grand in my 22 creed with
85.5 LRHT 26" 7twt
Peterson lr. Fed210. Mild load
46gr avg. 3300fps
Stopped there it 1 holes at 200yds
Four leaf clover with 5 shots.
But I started at 44gr and it shot great
Then 45 same thing then 46 and it was putting bullet in bullet. I stopped wasn't going to push my luck.
Hope this helps.
