I have a new .38Spl load development project in the works. I bought a few 110gr jhp from RMR - a discontinued Winchester bullet designed for standard pressure loads in short barrels - and there’s zero loading data published. I have pretty good selection of the mid-range powders (except the VV N3xx series) and a good testing platform (T/C 10” .357 barrel) and something kinda like a chronograph (Chrony F) so I should be good to start doing research and projectile dissecting.
The goal is a 25yd varmint dissuader with low recoil, low flash, good penetration in flesh but a miss hitting a solid barrier will stop it easily. No ricochet! Velocity goal is 800-1000fps depending on barrel length and pie plate rapid fire, each hand, unsupported in a dark alley.
Basically, a SilverTip.
