I like to handload both extremes for my Blackhawk. By that I mean I handload cowboy loads at 700 feet per second and I also load some powerful 357 magnums for the same gun.
For some reason this gun shoots lower velocities than what the handload books say it should, and slower than my other guns.
For example I have a Service Six with a 4 inch barrel that shoots 743 feet per second
My Blackhawk with 4 5/8 inch barrel shot 646 feet per second with the same handloads. Handloaded on the same day then chronographed on the same day.
I wonder why. The cylinder gap on my Blackhawk is .009", not too bad.
Now I'm looking for a powerful 357 handload. I can't get much more than 1200 feet per second.
Here's some of my 357 handloads (or at least the ones I chronographed)
All these are with 158 grain bullets. I have found out that the plated bullets shoot lower velocities than jacketed.
