300 WSM reloading

Has anyone had any experience with loading for a Browning A Bolt II in 300 WSM ?

Re: 300 WSM reloading

My friend and I worked up a load together for the 300WSM, his rifle being a Browning A-bolt II and mine a Tikka T3 Lite. We shot 165 grain Hornady SST over IMR4350 in Winchester brass and Win WLRMP primers. They were both new rifles and shot about the same at first, which was quite well, until they began to break in. Both rifles shot better with more rounds through them, but the Browning really turned into a tack driver after a hundred or so rounds. Steve, my buddy, dabbled with heavier bullets in his but didn't like them and returned to the 165 Hornady. BTW, you need to work up your load at safe pressure levels, but ours seem to like the high end of the load charts with the IMR4350.

Re: 300 WSM reloading

I am interested in this as well. I picked up my A-bolt in 300 WSM this winter and have been trying a few different bullets and powders, but haven't had any combo really stick out yet. I've been trying 168 and 180 ballistic tips and 180 accubonds and RL17, RL19, and H4831sc for powders. Most loads were an inch to inch and a half at 100 yards and a few groups here and there under an inch, but not consistently. Might have to try the IMR 4350, also seem to have read a little about H4350?

I like the 180 Accubond and want to eventually work up a load for it or something similar for a future elk hunt, but am also open to finding a load with one of the Berger bullets. I just get dizzy every time I look at the different options of Berger's, 168, 175, 185, 195, 210, etc. Do I just throw a dart and buy a box and try to get it to work? I get a little leery about the 210's just because of the short magazine of my Browning. Probably would be okay if I was using the gun as a target rifle and was okay with a single shot, but I would have to load that bullet too deep to fit the cartridge in the magazine for hunting purposes.

Mine likes IMR 4007 with 175 gr Berger VLD. I am at work and do not remember off hand the grains of powder but it shoots in the 1/4" range

You're probably best off using a bullet that is less sensitive to jumping to the lands. I had a browning Stainless stalker that shot great, the limiting factor was the short magazine.

Mine shot the best with Hornady 165 to 180 grainers with RL17 and H4350. 65.5 grains of H4350 with a CCI250 and a 180 SST in Win brass at OAL 2.855 this was a one hole load at 2950 fps with my Abolt. BTW H4350 worked with every bullet I tried in my Browning.

I believe you're on the right track with the powders you're using. The only thing I would say is concentrate a little more on finding a seating depth before you get too experimental with powder. You're going to be jumping a good bit. My method was to find the sweet spot for powder and then tune the seating depth in from magazine length in .020 increments to 2.800. I always found a load in there that worked.

Another good load for me was 168 Nosler Etip on top of 67-67.5 grains of RL17. this should get you to around 3200 fps with good accuracy once you find a seating depth. Mine liked 2.820 with the Etip in this load combo.

Re: 300 WSM reloading

With all of my wsm's RL17 gives phenomenal velocity, but I rarely get top-shelf accuracy.

I load for an HS Precision 7mm WSM, a Winchester M70 300 WSM, Savage 16 300 WSM, and a custom 338-300wsm based on a Winchester M70 action. I am getting incredible accuracy and extremely consistent velocities using H4350. Although the velocity is usually ~75 fps below max, I don't argue as the accuracy is just fantastic.

I'm shooting Barnes TTSX's and they seem to like to jump. Start off about 0.050" away from the lands and if you want to experiment from there. Although .050 seems to work in all the rifles I load for.

With the 300 WSM I have great luck with both the 168 TTSX and the 175 LRX seated .050 away, although my favorite is the 175 to get the .508 b.c.

Last night I zeroed my 338-300 wsm shooting the 210ttsx and H4350. 4 shots @ 300 yards had a vertical spread of 0.9" and a horizontal spread of 0.25 (overall ~0.3 MOA). I typically am holding that same accuracy out to 750 yards which is the max lethal range for this gun and I never had that kind of success with any of the RL powders. At least give H4350 it a try!
