300BlkTalk

I think the reference to the 30 carbine you’re thinking of is for the Lyman M die. They make other 30s but the carbine version works best for BLK.

How much SW are you using?

Be aware Speer is making two different 150g GD bullets in 308. Only one of them is 300BLK specific and is designed to expand at the lower velocity.

21 grains gives max pressure of 41322psi, MV=1658ft/s, 108% case fill. 105% was at 20.4 grains w/37225psi pmax, MV=1606.

8” barrel, COL=2.26”, 24.1 grains H2O case volume.

I don’t think it has anything for lot variations, at least I haven’t seen anything. The “b factor” is a mystery and may be part of the problem. The Combustion Coefficient seems to have the greatest effect. If I bring it down to 0.8 I get reasonable numbers. Also, I don’t have the data for 1680. It c...

IDK, if QL shows the settings for D063, but this is what's in GRTools

I’m using 24.1 grains of water. That’s measured in a converted LC trimed to 1.358”. I messed with the bullet “coating” but abandoned it because I thought the tool would think it was powder coated, and that seems like it would be worse than the STD jacketed type. I’ll try some other settings for the ...

It says... KABOOM! Nice MV though.

It only has generic D063, so maybe that’s the problem.

It was set to 8”. The tip of the bullet in the case drawing is pointing to that field. It seems like most of the data I enter is coming out on the hot side, some of it way hot... except fot the VV powders.

Has anyone played with Gordons Reloading Tool? It’s an free (beta) alternative to QL, but it has a pretty limited powder database. http://www.grtools.de It does have a bunch of Lovex & VV powders though, so I was looking at some 150GD loads to see how it compares to the data I could gather from ...
