375 Ruger

[cornbush]

I have a Ruger Alaskan on order with Ruger and I'm wondering which powders are getting the best results.
I'm going to stock up on components before it gets here and was hoping some of you were already loading for this little squirrel gun.
My main use will be for elk, and the occasional squirrel or rabbit, planning on using mostly 270gr bullets.

Please send me pictures of the aftermath of using that gun on a squirel or rabbit.

It will be a few weeks, the model I have coming is not in production right now.
I do know that 375 H&H, 416 Rigby and 458 win mag do the trick though.

I'd check the Hodgdon site & others for powders they list. Should be some common ones you can use for other applications.

I know what some of the manuals list....H380, 4895, 4350, 3031, W748 as well as some Ramshot and reloader........ I'm just wondering if anyone loading for this has had any that really shined?

I have no experience with .375 Ruger myself, but based on my success with H4350 in my .375 H&H I'd probably start with that. Another good one might be Reloader 17.

CONSULT YOUR LOADING MANUALS BEFORE LOADING ANY OF THE ABOVE BULLET/POWDER COMBOs

I can tell you from experience that my 375H&H loves (really loves) N560
Note also that ~106-108% fill indicates powder and bullet meet, but do not appreciably compress.
