    Mine likes RL 22 and RL 17 behind a 185 Berger or a 180 Interbond. I've never played with any other combinations because both bullets shot well with both powders.

    The Bergers with 63.0 grains of RL 17 shoot 1/2 minute 3 shot groups and 3/4 minute 5 shot groups. I've actually shot many 7 shot groups with this load and they were all 3/4 minute as well so I'm confident it's a 1/2 minute cold bore gun and a 3/4 minute higher volume shooter.

    I don't remember how much RL 22 I put behind the 180 grain Interbond but 3 different powder charges all shot less than MOA.

    The gun is a lightweight Browning X Bolt.

    I've had good results with IMR 4350 and not so good with IMR 4064 and RL17 but each rifle is different. Working on a new H4350 load presently. My buddy has a RL15 load that's been working pretty well for him.gun)

    Many different combinations will work well in the 300 WSM. I first found that my Model 70 Winchester would shoot 165 grain Nosler Accubonds and 165 Nosler Partitions very well with RL-19. After this I found that this gun would shoot 155 grain and 168 grain Sierra Match bullets very,very well with RL-19,Norma cases and WLRM primer.


    I am now loading 185 Bergers, 190 Bergers with Norma cases, and both N165 and IMR-7828. 69 grains of N165 along with 190 Bergers gave me 2867 ft/sec and very good accuracy.

    These are just a few loads that I have worked with. It depends on what you want to shoot. I have also worked up some great loads with Barnes 168 TSX bullets using N550 and RL-17 powders. If you want more specifics let me know.

    If you really want to turn your 300 WSM into a hammer, try some Berger 215 hybrids or 230 OTM tacticals with a proper charge of 7828SSC. You should be able to push 230's to around 2700 and the 215s to around 2800 fps. I guarantee you can't push a 165, 180 or 200 grain load fast enough in a 300 WSM to match these heavies for retained energy and wind resistance.

    what barrel length are we talking about here? A 230grain bullet in a wsm at 2700fps?

    I have shot everything from 150's up to 208's in mine. I don't recall the 150 load but the 168's shot best for me with H414 and imr4350 with the edge going to 414. I moved on to 180's next with 7828 and had good results. My rifle hated 190 smks so I tried the 208 amax and h4831 next and that has been what I have shot since. I am getting 2950 and it is a hammer on whitetails. I started with norma brass and fed 215m, but for the 208 load I tried some nosler brass and fed 210m and have been very happy. My velocity spreads really tightened up going to the 210m primers.
