Gentlemen,
After several months of load devlopment I have come up with a very accurate cast bullet load for my 1982 4" 586 no dash I picked up earlier this year.This gun is extremley tight and showed very little use when I bought it. As those of you who own 4" 586 and 686 guns know, they balance very well for off hand shooting. The load consists of bullets cast of wheel weights from RCBS mould 38-150-SWC which come out at 156 grains for me. The lube is LBT Blue and they are sized .357 and primers are CCI 550 to ignite 14.5 grains of H-4227 for about 1175 FPS. Since H-4227 is no longer made i'll have to come up with a load for IMR-4227 soon. 2400 did not give me the results 4227 has. I got the idea for this powder from articles by John Taffin. When i'm doing my part, this load puts 4 out of 5 rounds in 3/8" to 7/16" groups at 15 yards off hand, consistantly. Also of note is that the shooter, me, is 65 years old with trifocals. The load and gun combination is just that good! There is very little leading after 50 plus rounds which cleans up with just a few passses of a brass brush. As someone once said, "you don't sell a gun that makes you look good"and this one won't be going any where!
For those of you who have been shooting L frames longer than me, why do you belive that they are just so accurate? Maybe it is just the super tight specs. The cylinder gap is .002 on this gun. Thanks for your time and hope this load will serve some of you.
Jim
