338-378 Wby 300smk loading help
I'm new here and I am looking for help shooting heavy bullets out of my Wby Accumark 338-378. I heard so much about the 300smk that I would like to try some. I Got some samples from Sierra while I was at the SHOT Show in Vegas. I have had good success with RL25 but I will try what ever has worked well for others. I want to shoot elk out to 800 yards or more. Any help is appreciated.
