I bought this mold to make low recoil, economical, practice ammo for 5 shot snubs and to maybe see what kind of accuracy I can get with it in my .357s.
I have cast some up with WDWW, sized them to .358", and lubed them with LBT blue soft. I loaded them in mixed .38 cases over 4.5gr of 700x. This is a "max" regular pressure load for a .38spl. The books show 4.8gr for +p with 110gr jacketed. These will be shot from a .357 for velocity testing, then in only +p rated .38s (all I own), hence no real "work up" to "max". Once I have a baseline of velocity and have the Ultra-Dot on paper, I plan to work loads in .2gr increments, and play with size, lube, alloy, etc. for best groups. I will try them in .357 brass too.
Does anybody already have experience with this boolit and care to share some good loads? Doesn't have to be with 700x, but I have over 8lbs of it.
