I currently use a 5 1/2" SS Bisley in 45 LC to deer hunt with I shoot the Speer Gold Dot (Deep Curl) 250g. JHP at 1200 fps. The deer taken (3) have shown severe wounds (expansion) with complete penetration in all cases. Would like to hear others experiences and specific ammunition uses in this great old cartridge (which Ruger has kept alive with its great revolvers!)
