Home Forums Reloading Big Game Rifles Reccomend powder for 7 and 300 Mag

What newer powder would you recommend for 300 win mag and 7mm mag.

I have limited R22 and H4831SC. I am trying to find a more readily available powder for both magnums. Ive heard good things about Ramshot Magnum but never used it.

In the 300 win mag, im planning on using a Barnes 175 LRX.

In the 7mm mag I will use either a 145 LRX or 162 ELDX.

Thanks.
