Hi, Anybody used /using this powder for rifle loads, Just printed off the data from their site, but would be grateful for any of your comments, I'm reloading/shooting .270W & 7mm WSM, In this powder range, Thanks in advance for any input, Steve.

I've played with it a bit in 300 win, 300 wby, and 30-378. It never gave me magically accurate loads but then again was not bad either. I just decided to go back to my fav powders in those calibers. I did find it to be a bit slower than their data....but it may have just been that lot of powder. I remember in 300 win mag their max load was about 100 fps slower than other powders in the gun. I wound up almost 3 grains higher than their load to match the speed of re22 and h1000 with no pressure signs.

I used magnum in my 257 wby mag and this is what I got........

I use Magnum for 140 gr bullets in my .264 WM with excellent results. IMR 7828ssc works better for the 120 gr. bullets.

I am currently working up loads using Magnum with 140 and 150 gr bullets in a friends 270 WSM.

In both rifles the CHE and velocity increases are very linear as the powder charge is increased and accuracy has been great.

I can only guess regarding the .270 Win. and have no experience with the 7 WSM. I'd say that Magnum is too slow for the .270. It's slower than Retumbo and IMR-7828 which I've used in my .270 WSM with 150 gr bullets. My .270 Win. load is a 150 gr. Partition with 57 gr. of Rldr-22 and I get ~ 2930 fps. I have played with 130 gr. Barnes bullets in the .270 WSM but the only powder I've tried there is Rldr-19. which seems to work pretty good. I'd say your powders are too slow for the .270 Win.
