Daryl,

Just after I read your last posting I opened the latest copy of Handloader and read the article on the Lipsey’s Ruger Blackhawk in 45 Long Colt (& 45 ACP). In that article Brian Pearce is showing 21.5 grs of H110 with a Lyman 454629 318 gr bullet as being within 45 Colt +P pressures i.e. 23,000 psi. That would make my load of 21 grs with a 300 gr bullet quite conservative considering the strength of the action. Considering that all I’m doing is punching paper I’ve never tried to go further but for your purposes I can see why you want all the wallop you can get. It’s a pity I never chronographed my load. However, I checked my notes and the 185 gr bullet over 11 grs of Unique is roughly averaging 1,350 fps out of the Trapper over my Chrony.

Like 9.3, I really enjoy my Trapper.
