Good eye! Chad put an M16 extractor in the bolt
I put my 6-24 Sightron SIII on it.
Thanks Rich. Got my brass today too. Looked like a rifle drs writing!
Ran the first rounds down the Max today with 6 different powders. I loaded mostly 175 EHs and a few 195 EOLs
Top speed hit with 175 was with RL26 at 3115' and no pressure issues.
Tops with the 195 was with N570 at 2969' also no pressure issues.
With Retumbo, RL23, h1000, and ramshot, around 3050' is doable with the 175-180 class. I only loaded one setting depth for everything and the 4 I grouped all shot 1/2" so it looks promising with some load developement.
We've found that the 8.5 Rock barrels take about 2 more grains to pressure up than a Bart or Krieger though!
What powders would you use for the 155-160 Gr class bullets?
Good question? Maybe something like H100V, N550, RL17, etc
I'd try IMR 7828.
I’m going to try N565 with the 155 federal edge tlr
I have 250 of the edge TLR bullets to try out with my 7mm Sherman Max when I get it built. I’m hoping to get 3200-3250 FPS with them. If they shoot accurately, I really think that they will be an all around good bullet. Going to try H4831SC and RL17 I do believe.
I don't think you'll pressure up with 4831!
Dang it..fine haha. I still have a bunch of H1000 but don’t know if that will be good with the lighter bullets.
It won't either.
I think Hy100v might be a good choice
565 probably won’t either. What about rl23 rich?
