I am running a 32" 1:7 twist Bartlein barrel. Retumbo is almost impossible to get so would really like some RL33 RL 50 or anything else. Thanks you!

I was able to get N570 and am running 129.3gr in my standard 375CT. Rumor has it more N570 will be available before the end of the year. I am running Bartlein 1-7 32in also.
Bullet weight helps...
For reference, I ran a 130gr load of returns under and cutting edge 377 for forming load. It ran 2980ish. I’m switching bullets now that all my brass is formed so that’s as good as I can get you for now

You're absolutely correct sir! I was looking for any loads but I did order the cutting edge 350 Lasers to start with. I am currently fireforming with 130 gr of retumbo (very little left) and 350 sierra matchkings
Same charge I formed with using the 377cutting edge
What COL are you using for the 350gr matchkings? Any pressure at 130gr for your fireforming loads? I should be able to start putting together my fire forming loads here in a few weeks when I get unpacked and setup again. Sounds like Robert Vestal did about 6 of the BAS rifles all around the same time. My friend and I are 2 of them. Can't wait to get some trigger time on it!
4.100 coal. No pressure at all
Cool. How did your fire form loads shoot? I got 50 rounds loaded up for this weekend.
n570 in stock at powder valley right now. May be the perfect powder for the Cheytacs. Has been for me.
Nice! I've got 8lbs of 20N29 to try in mine with the 400gr solids
How many grains of rl33 are in your 402 load?
