Earlier this year I used Ramshot Grand with the heavier 225 gr Hornady from the 300 Win Mag. It worked out real well with excellent velocity, accuracy and tight SD. My notes say 2812 fps with the SD of 7 fps - that was a short string of five shots though.
We only had a little Grand at the shop, so when we got here to Oklahoma, I bought 8 pounds of the stuff. It's proven very useful in my 25-06 and my 7mm Rem Mag rifles.
That's good to hear. I started using it in the 6.5 Wby RPM with excellent speed, SD's and accuracy. I plan on trying it in my 338 RUM and Sue's 30 Nosler.
