Reloader 17 is THE powder for the 300 WSM. H4831 does decent in mine as well as H-4350.
I've had excellent results with IMR 4007-SSC in my 325. Equaled factory 200gr Accubond load accuracy and velocity at 2950fps. This combo works in my gun I couldn't get 180gr tsx's to shoot for squat. I understand they are picky about off the lands measurement. I can't remember the exact figure but I think Barnes recommends .50 off the lands?? 220gr Gamekings with 4007SSC gives about same results at 2800fps. H4350 did not give the velocity or accuracy. I've not tried RL-17 and probably won't.
I wish I could get my hands on 7mm 168. And 270 150s
anyone here shoot and reload for 300wsm? i have a tikka t3 lite in 300wsm and now that spring bear season is over i want to start testing and making some loads up for it. I have been shooting federal 180gr trophy bonds (orange tip nickle case) and it seems to like those, i have a 3 shot quarter sized group at 100 yards with them, but i am really wanting to get into reloading more. any ideas or load recipes to try would be awesome!
Your Tikka should shoot a lot of loads that well or better. Littlebuf has that same gun I think and he has a really good load for it. Send me a text if you want and I can help you get a load dialed. I have a full reloading setup and a 100 yd range to test.
