I've been reloading since 2001, (9, 40, 45, 223, 300blk, 308). I just bought 38/357 dies and last week I found out about lite loads of H-110 for 357. That low power load will not burn completely by the time the bullet passes the gap and will fizzle out. Set that powder aside and tried 4227 for 38, loaded some different loads but yet to test them.
People have blown up guns with light loads of H110/W296, exact same powder other than lot to lot differences. I personally don't like that powder due to how sensitive it is to temperature. I would never use it if you can't have a safe load at 90% or greater fill density. If you use it and you develop loads when the temperature is hot, and your rounds have been in the heat long enough to stabilize, you are safe to shoot in lower temps. Never do in the other direction.

Does anyone know if the 15-2 with 8" barrel tends to prefer one weight or manufacturer' bullet? I shot some 158 gr. Sierra JHC sitting on 14.3 gr. H110. Flash seemed excessive when indoors and the burn was not very clean. Velocities were very close to the Hornady data. I have more Sierra 158 gr. JHC, some Sierra 140 gr. JHC, and Hornady 158 gr. XTP. The ultimate goal is a good hunting load.
