I think N133, N530 and 2015 are "short".

Anyone know what IMR 3031 and Norma 201 looks like?

.0885 for IMR 3031 (give or take)

by the way ar15barrels, now that I posted this thread will die

[ocabj]

as well as blending powders..... Winchester blends its 5.56mm whitebox, q3131 and q3131A

Someone told me about how they pulled some .30-06 LC 69 and each round had mixed extruded/stick and ball powder.

IMR3031 top, Varget bottom




PDQ: thx


PS. IMR3031 fits the bill, now, I just need to find some and TEST. Whether it is good or not, we'll see. Anyone got some in San Diego?

Make sure you run temperature variation tests at long range.
You will find out that it's more temp sensetive than Varget.

Temp testing at 100yds won't tell you much so move out to about 500yds.

Will do.

But I will do 10-20 rounds average velocity difference @ shorter distance first. I will probably interlace them in the firing sequence too.

And I will probably give Varget another try, since I want to see how it performs in my new R&D custom.

I don't understand this obsession with duplicating military rounds. It won't buy you points or shrink your groups. It's a .308 ffs, the load development's been done, for quite some time.

For semi-auto .308 shooters, it's nice piece of mind. You know that military 7.62 NATO rounds are designed to work in your rifles, whether that be an FAL, M1A, G3, etc...

It's just good practice to go with what you know is going to work well and be safe...
