I had a friend just getting started in the Gun building buisness. I gave him a Mauser action and he built me a .375 Ruger. The down fall is I have very little Reloading data. I REALLY LIKE 7828 POWDERS FOR MY BIG GUNS. DOES ANY ONE OUT THERE HAVE DATA FOR IMR 7828 ON THE .375 RUGER? This is scarry so please try to make it stuff you've tried!
