Re: has anyone used IMR4831 with 210 Bergers in a 300WSM?
Thank you, brentc.
I'm going to get some IMR7828ssc when I get back to my local shop. I saw it Monday when I was there. It shows up in my Barnes, Berger, and Nosler manuals rather frequently.
My RL-22 load is pretty accurate (.422'), but velocity is only 2622 avg.
Do you use mag primers with IMR7828ssc or regular primers since it's a ssc?
