I have a ruger american in 450 bushmaster but have no experience with reloading the caliber. I am using the barnes 275 gr TSX and h110. I have read in several sites that the caliber is loaded to pressures consistent with the ar15 platform, and can be safely loaded warmer. Not chasing high velocity, but would like to know generally what is safe. Hodgens says 37.6 grains is max with this bullet in an ar. I have gone to 40.0 gr with no signs of pressure, and don't want to go farther, but would like to get the groups feelings on this load. Have reloaded rifle, handgun, and shotguns for 50 years including all the magnum handguns, and rifles up to the 458 Lott.
