With all the lovers of this powder in the wsm's I would think it would work with the 300 win mag too. There is no data I could find at Accurates site.
I guess if you could give some loads for the wsm I could cross reference a bit using quick load. thanks for any help/experience.

Kraky I tried some in a 308 Norma and found it to be very similar to the old Win 785 powder which was close to H450. Not sure that helps you or not .

Thanks for giving it a try for me. I don't have those 2 powders in quick load to try and cross reference. I found some 300wsm data and hopefully have a good cross ref with quickload and have some 180's loaded for the 300 win mag at 78 and 79 grains. My mag has freebore and I can usually go 1-2 grains more than most published data so I'm not too far above 300 wsm data....if anyone else has input I'd love to hear it. Thanks Don

Kraky,

There are a couple of loads about half way down the page. They seem to be from Berger.

Here is another: 300 WM load

Thanks for the help. I had emailed ramshot and they got back within 24 hours. Quickload was right about the forecast. The 78 grain load did 2920 and the 79 grain load did 2955. There would be room to go up a bit because of the freebore. Ramshot said 80 was probably max. I didn't get RL22 type accuracy with the 180 bt but will probably play with a couple tsx's now. It wasn't a real clean burning powder but not dirty either. That little tikka t3 with 180's is an ass kicker being just 7#'s 3oz with scope. I've got a couple buddies I'll be loading wsm's for so I'm glad I have the powder on hand to play with a bit.
