Thread: 357 mag subsonic reloading data

so longer barrel length will SLOW load down,after a point...X amount of inches the powder burning and pressure good,then acceleration stops and slowing begins...this is why some fellas have issues with subsonic .22lr giving out sonic crack when they have really short barrels......a long barrel .22lr very very very seldom has the same issue.
I havent loaded .357 but did tootoo with 7.62x39mm and subsonic loads but used trail boss which you have used....it is still around to purchase..you sound like its working BETTER for you than most other people...so grab some more.
forget OAL of .38 special...my recomendation is to use the load you already have with X projectile...the load that shoots best and set up your seating die using that length.... your data for .38 Vs 357 will be different only in % of case filled
back of my head there is warning bells re 296......pretty sure its the one that is use ONLY at full capacity.....could be wrong but please check before trying lighter load using it.
