My quest for a new hunting rifle may have come to an end. I recently acquired a Browning AB3 in 300wm.
It's decidedly more horsepower than I need for coyote, javalina and deer here in the southwest, but it's got a lot of features that I wanted in a hunting rifle and in a pretty nice package.
It looks like if I really wanted to put the pedal to the metal, I could push a 150gr to 3200-3300fps but something around 2900fps sounds much more pleasant.
I poked around Alliant's website and it looks like RL15 may work well. A max charge of 64gr giving 3058fps from a 24" barrel (mine's a 26"). I already have RL15 (and IMR4064 &3031 on hand) which is serendipitous.
I'm not too hung up on 2900fps as a magical number, if I hit 3k+ and accuracy is excellent and recoil not abusive, I'll be tickled pink. Just a "thereabouts" number.
So what powders are you guys using to take a little off the top on the 300? I may also go ahead and thread the muzzle for a break, I hunt with earpro so the increase noise shouldn't be a significant issue.
