FF 30BR with Varget??

[jvshiver]

Anyone ever fire formed they’re 30 BR brass with Varget? Reason I ask is because I have two new Barrels on the way and a boatload of extra Varget and I would rather use it for fire forming than use up my 4198 or N130.

How did it go?
I have fire formed 30br with V133, and Vv135.
Im sure what you got would work

I will let you know hopefully next week, I don’t see how it can’t work tho.

I agree

Just a thought...maybe use heavier projectiles for fire forming - betcha have some 150g hunting bullets lying around?

I've f-formed 30BR cases with a case full of 748 several times. It's right there with Varget on the burn rate chart...though the load density is quite different due to the physical differences of the powder. A substantial amount of jam-seat and pretty stout neck tension always stack the odds in your favor when f-forming...doubly so with too-slow powders. A bit more bullet weight doesn't hurt either in that scenario.

You won't be able to get enough Varget in there to hurt anything, that's for sure.

Good shootin' -Al

What kind of powder charge are you thinking about using? I've got a new 30br and some extra varget, same as you and rather not use the N130. Might give this a go as well.

CFE BLK works well for fireforming it's usually available and cheaper also throws really good.

Another option is RL-7. I shoot it in my 30 BR for matches. Seems to work as good as 4198 and 130. If you can find some it would FF just fine.

FWIW

I am fire forming some 30BR brass with a moderate load of 34.5 gr. of A-2015 @ 2750 FPS. Probably could not get enough in the case to reach above 3000 FPS but it is crazy accurate at the slower speeds.

Probably see how much I can pour quickly and go from there, should be able to put 32gr or more in there easily. I don’t expect a bunch of speed out of it but will be good enough to expand brass, straighten my expanded necks and put a little carbon inside the necks. I don’t think there is any way to over pressure with the Varget and the big 30 cal opening

Good to know, thank you!

Just a follow up on Varget, is it ideal? Nah, but if you have a bunch of it and a new barrel and 200 pcs of new brass, it works, shoulders look good and necks are straight. I used 36.0 gr because it is a case full and can be poured quick without a drop tube. Barrel started off at 2660 with 116s and after 50 rds so far same load is up to 2700. Definitely not a speed demon but surprisingly it’s shooting a small group at 100

It's hard to make a 30BR shoot bad
