I bought my first .41 the first day I worked at the gunshop as gunsmith. The boss said I had a charge account so I paid $85 for a used Blackhawk, old model 4 5/8" Blue. I handloaded it hot, mild and in between and became accustomed to hitting things I aimed at with it. I had it brush nickled and made grips and had a brother in law talk me out of it. He still won't sell it back...at triple what he paid.
As a deputy sheriff, I carried a 4"nickle Model 58, and bought a couple more Blackhawks and eventually bought a lump of rusted river-found New Model Blackhawk .357 6" and turned it into the revolver pictured above. This was late '80s when Ross Seyfried was writing of big, heavy, cast slugs in big bore revolvers and I became a convert with the custom BH. The barrel is a 1-14 Douglas blank and has never shot any bullet but 255 gr. LBT, quenched wheel weights. The sights are one fixed (75yard) and one folding (175yards) zeros and if anybody wants to go $20 hit or miss on a propane bottle at 400 yards. Come on! The range is open.
Penetration on elk sized game and larger is clear through with a ricochet on the other side.
In my opinion, the 41 bore diameter is the first useable long-heavy caliber and gives great case capacity with the longer bullets.
I've got two other .41s that shoots 'standard' 210 Jacketed bullets just fine, but the BH is at another level.
