New Contest Starting Now! This Target Haunts Me
Tell us about the one that got away, the flier that ruined your group, the zero that drifted, the shot you still see when you close your eyes. Winner will receive a free scope!
My 300 will be home soon!I have some loads from before the rebuild, but for a sporter barrel. Looking for loads for 190's & 200's SMK's, AMAX. I'll be running a 26" Rock barrel 1:11. Thanks for the replys.
Take your pick..... I lost count on how many different powders I have for mine. R22 and h1000 for the bullet sizes you mentioned. Also h4831 and ram shot mag
I have an 11 twist Obermeyer for my 300 WM and it loves RL-22 with 190 VLD's (0.30 MOA at 600 yards) and H4831sc with 210 VLD's (0.40 MOA at 600 yards). I would try H4831sc first since it's temp stable. But hard to argue the results almost every 300 WM owner gets with RL22? Great powder.
R22 is a love / hate relationship. My .300's love it but I hate it's temp sensitivity. It's gotten so bad that I actually load rounds in the summer and make sure they are chronographed and put long way down range that day bc I can't stsnd it's temp effects. For ex., I made a screw up and ranged a buck at 413 yards. I doped my scope and barely hit him (clean kill though) only to realize he was 327 yards away. I hit LOW! Ran the #'s and I was 2907 that 60 degree day I loaded it. That 25 degree morning I was at around 2760. 143 fps!
AS, that's the same thing with r-17. Too sensitive on temps. It's not worth the time and hassle of developing a load for every 10* on the thermometer. Forget that when I can run h1000 and some 190/208/210's all year long and have consistent dope.
