The data I have seen shows that you'll be OK. If in doubt, load one at 65 as a fouler - if it shows pressure at all you'll know not to move forward.Ive been leaning towards h4831scc just wasnt sure. Its a rem 700 vls that was rechambered from 308 to 300wsm. It has a 25.5in barrel with thruster brake. I made a few loads with 4831 tonight but just not sure when ill make it out to test.
Ive loaded 3 at 66 to 68 in half grain increments. Should be a good starting point. Hopfully im not starting to hot.
That's impressive, the best I've done with 215 is 2700 FPS out of 24". I have a pound of RL-17 to try.Neither powder. For optimal velocity use RL-17.
I put together a load for my friend's 22" 300 WSM with the 230 Berger. 2725 fps with 61 gr of RL-17. OAL was 2.8" to fit and feed from the magazine.
When I grow up, I want to be able to hunt and fish (I suck at fly fishing at the moment) like Don.Feenix,
It surprised me too. Don said make me a LR load. I had plenty of 230s on hand so I seated them deeply in the case and worked up. He flattened a cow elk with it at 300 yd. Hardly a LR shot but Don at 85 yrs young did well.
He is now 87 and still hunting and fly fishing. He has a Az antelope hunt and has the Champs permit so he can shoot from the vehicle. He is not much of a hiker anymore. Have a braked 257 I may give him to use for this hunt. That Brownig 300 wsm even with the Boss brake is too much of a kicker for window shooting.
Nice I have had good luck with the 180 VLD and 180 Accubond with 4350. And guess where? Right about 63gr. Seems around 2850 is always a good spot with the 300 WSM. With a load of RL17 I can get the 210 VLD to 2850 without much problem either.Tested again this weekend and I had pretty good luck I think. I stuck with the h4350 because it was at lower pressures and had more velocity than 4831sc.
2x 62.5gr- 2876, 2853
2x 63gr- 2935, 2880
2x 63.5gr- 2890, 2896
I fired 3 more at 63.5 and with all five shots there was a ES of 10fps. There were no pressure signs and extraction was smooth.
All five shots were touching if not in the same hole at 100yd. I am yet to make it out to the longest mile in Edson or a cutline on my next fishing trip but with this info it should hold together well.
