When I first started loading the .357 mag in the mid 70's, I used 2400 with 110 gr. JHP's loaded to about the max. As the years passed, I switched to 158 gr. JHP's and Red Dot, Unique, and Blue Dot in moderate to moderately heavy loads. The two faster powders gave good, consistent, moderate loads, but watered down velocities. Blue Dot gave acceptable to me velocity, but at times also gave inconsistent results & lots of blast. Mag primers were used for all because my manual data at the time called for them.
Recently, I again bought a pound of 2400, and wanting a moderately heavy load, but one with less than one at full throttle with a 158 gr. JHP , I tried, and have for now, setted on 13.5 grs with a WSP standard primer. From my 4 " bbl. GP100, it gives in double action mode, very managable recoil & blast, a pleasing " bark ", & good accuracy. It also seems to burn very cleanly, leaving very little unburned powder residue. I haven't clocked it yet, but it should be in the 1150 fps ballpark, which is what I desire. Do any of you use a similar load with 2400 in your .357 mag loads at about 90 % max ? Thanks.
