300 win mag

[SEMNshooter]

I am going to start loading for the 300 win mag and have a few questions. I have been loading for a while, just never for this. I have some IMR 4831 on hand that I use for 30-06 and was wondering if it is a good powder for the 300 too. I plan on using 180 gn sierra's for an upcoming deer hunt. Any other opinions on powders to try? I'm not looking for specific load data, just general opinions on the powder in this application. I am assuming mag primers are needed?

Both IMR 4350 & IMR 4831 are time proven favorites for .300 Win Mag.

If you have IMR 4831, Mag primers & 180 grainers on hand, sounds like you have all the right stuff to get started.
Good luck on your hunt!

I appreciate the response. I have both IMR 4831 and 4350 in the cabinet, I think I'll start with the 4831 and work from there. I have a bunch of brass ready to load and we'll see where it goes from there.

i have been using IMR7828 and nosler partitions and have had great results. 180 grain nosler partition, over 74.5 grains of IMR 7828, and a magnum primer. i have been incredibly satisfied with my groups with this recipe............i can't wait to see the results of it on a deer myself!!

I have a 300 Win M 70. I started with IMR 4350 and never needed to look at others. Not to say that others won't be just as good, but I never needed to try them.

Never used IMR 4831. I tried H4831sc in 300wm and never could get an accurate load. If you wanted to try something different, grab a lb of R22.

I've used both IMR 4831 and Hodgdon H1000 with great success. I haven't used 4350, simply as the other two worked great. Having said that, the 4350 comes highly recommended. I've used RL22 as well-- great with some bullet combos, but not as consistenly good for me with a wider variety of bullets (i.e. weights, make, etc.) as is the 4831....

I just started loading for the 300 win as well and so far 7828SSC has proven to be very accurate at the lower end of the recommended charges. However I am only sending the 180 grain bullet at 2550fps and the 165 grain bullets at 2700fps. I am planning on trying some RL 22 after the season. Might as well take advantage of the magnum part of it.
