With those powders no. I think with n570 in a 22” your gonna be about limited out around 2900. The h1000 and retumbo I think will be low 2800’s. I’ve played with the 245 in two other 30N’s getting same thing same results. I even started shooting the 7 saum with the heavy’s and 195.
I shot two with them in the last 4 months. Both pass throughs. Didn’t take a step. One was about 140 the other around 200. Holes were around 1.5” exit. Both in the shoulders. Smaller one was close around 100. The bigger one was around 350 or so same results. I like it so much now I’ve...
I would go LA with a saum. Forget the prc if you load. If you gonna use factory then go prc. LA allows you to use it later for other cartridges and you will eventually get the itch to swap barrels. There’s very little difference in weight between the two action lengths.
Funny thing. Working on a load for a new barrel in 6mm CM 20” Krieger 4 groove 7.5” twist for a shoot coming up in 3 weeks.
Anyways here’s a couple pics just before the eclipse and one during the eclipse. I couldn’t see the 100 yard target lol.
