What load are you shooting? I've shot a .445 Supermag for about 13 years now and have had the metallic taste in my mouth from the concussion of heavy loads going off. Rough on the shooter, firearm, and anyone standing close. The heavy loads were never any fun on a 40 round match, much less the 60 or 80 round matches.

Decided to just load the .445 a little warm of middle which still is hotter than some of the firewall .44 mag loads.
