Anyone have load data for a 300win mag with win748 powder? Is the 748 a good powder for that much gun, if not what would you recommend? Thanks
 
No, Win748 is not a good powder for the 300 Win Mag. I couldn't find any load data with that powder in that cartage at all. I would recommend Alliant Reloder 22 or one of the 4831 choices but not 748.
 
Well I tried to find some reloader 22, but SURPRISE, all out. They did have some reloader 19 so I got a pound of that. The Lyman book the store had on the counter had a recipe for the reloader 19, so I figured it would be at least a starting point. I plan on getting the reloader 22 as soon as I can find some. Thanks again.
 
Reloder 19 will work just fine. Work up carefully and you'll be happy with it. The Speer manual shows a max load of 76 grains for their 180 grain bullet but I don't know if I'd be willing to go that high. The listed starting charge is 72 grains but I personally would start a little lower, maybe 71 grains and set max at around 74 or 75 depending on what the cartridge looked like after being fired. I'd just try to find the most accurate load and enjoy the hobby.
 
IMR 4350 shoots good out of my .300 WM. RL 22 and H4831SC perform good also. W748 is for small cartridges. Look for slower burning powder.
 
I use Reloder 22, IMR4831, IMR4350 and H4831SC. Probably the H4831SC is the most user friendly, it meters pretty well. Seems to give me the best accuracy with 165 gr Noslers.
 
Rbreb I read your post at first that you said most fur friendly and not user friendly. I was about to say I don't think 300 win mag and fur friendly can go in the same sentence.
 
Thanks for all the help with this. The more I read the more I'm figuring out this powder stuff. The slower burning powder is for the bigger calibers, it kinda makes since if you think about it. Also, Jarhead and Rbreb, I don't think the 300wm is friendly with anything, but it sure is fun to shoot.
 
What I meant by user friendly for the H4831SC is that it meters fairly well. I can crank out quite a few rounds quickly. When I lived in Colorado I would shoot Marmots with my 300WM out to 1000 yards or better. The bigger heavier bullets worked well for the mountainous terrain and swirling winds.
Fur friendly? [beeep] no!! Not even on Elk!
