300 RUM 215 Berger Load work up

[cmahoney]

Just shot this string today, the rifle has a 28” Krieger barrel, new Norma brass, CCI 250 primers, H1000 and bullets seated .015 off the lands.

Didn’t see any pressure signs. I was going to focus on that node between 90.4 and 90.8 grains. The 88.2-88.8 node is also plenty fast for me.

I’m looking for any opinions or quick load guys who want to chime in.

Thanks

Got a pic of the target with shots labeled? 88.2-88.8 is where I’d start.

Didn’t label the shots, I was using my magneto speed and really just looking for a velocity node.

I would retest 88.2-89 and see what groups and velocity are.

Here is the 100 yard target, the fliers were totally me. I hope that seating depth works, that rifle is expensive to shoot.

I'd try the lower node first. Plenty of speed to kill anything on 4 legs as far as you'd want to shoot. Better off safe when it comes to a hunting load IMHO.

Interesting approach going with velocity node first. Is this because you only have a 100 yard range? First I've heard of doing this rather than a ladder test at distance. Just trying to learn.

No, just trying some of this method to try and save components.
