.41 Mag reload

SCorvers

Bought me a brandy new Black Hawk .41 w/ 4 5/8" barrel. I am a happy man.[:D]
I picked up some cast bullets advertised as 210 gr. but when actually weighed came in between 203-205. My newest Lyman manual only shows particulars for a 215 gr cast bullet. I figgered I would reduce the starting load by about 5% to get started. Would this be reasonable? And does anybody have a favorite plinking load for this round? I'll more than likely use AA#9 or 2400.

I'll check on that for you when I get home from work . Do you think
win. 231 or something like Bullseye would be a better powder ?
Just got done looking for loads with that powder for the 44 mag.
Seems to me ( I. M. H. O. ) that those powders are more suited to
full power jacketed bullet loads [B)]

I load 8.5 gr of Unique with 215 gr cast lead bullets. This is about 850 fps. The slower powders such as 2400 and #9 are good for full power loads but are are going to be irratic at low pressures. The 850 fps load is close to the origonal police load that was made when they were pushing the S&W 58 as a duty weapon.

17.5gr of 2400 behind a 200gr HP (did not say if it was jacketed) giving 1420fps @ 34,700psi. - OAL - 1.580"

I have been using Hodgdon Titegroup for my .41 plinking loads and it works great. It is clean buring and Not position sensitive. I load 5.5g with a standard large pistol primers and a 215g LSWC. Titegroup also runs $1.00-$2.00 cheaper per pound than most others and you use less. It does well for 10mm, 9mm, 45acp and 40 S&W (these are the ones that I have tried). As long as you are in the medium velocity range it isn't for hot loads. The Hodgdon reloading manual shows 4.5 to 5.5 grians for both 200g and 215g loads. The 200g 4.5g @ 897fps 11,400 cup to 5.5g @ 1030fps 15,300 cup. The 215g 4.5g @ 882fps 12,800 cup to 5.5g @ 1004fps 17,400 cup. I use 5.5g out of my S&W 57 6" and it averages 895fps.

When the Blackhawk first came out in .41 magnum, I bought one with a 6 1/2" barrel. One of the loads that I shot in it had a 210 grain cast bullet in R-P cases, a Winchest large pistol primer and 7.2 grains of Unique powder. That load shot well for me and Was a comfortable load to boot. It went around 900 to 925 fps as I remember. I tried to keep cast bullet loads under 1000 fps. in those days, I hate to have to clean lead out of a barrel. Right now I have a S&W Model 57 and I shoot only jacketed bullets in it. Mostly the Speer 200 grain JSWC. For jacketed bullets I use H110 and 2400 powders-both give excellent accuracy. I may try some hard cast lead bullets again sometime.

The numbers I posted earlier are straight from the respective web site. However, the velocities seem really high for a lead bullet. I'm pretty sure that a cast bullet traveling at that rate will lead up a barrel pretty quickly. Be careful.
