Does anyone know the dimensions of the rainstorm .30 or .357 hammer spring??
Thanks Ken, appreciate that. Thanks RKR for those stats on yours… the one I have is just a bit more stiff and I get good.power and efficiency but it’s just a bit too big a wire and limits the adjustability due to bind.

Were you able to find out what mold you or your friend were casting for the RS .30 cal?
I have a stainless steel.072 wire diameter in it now. I cut several in various lengths and tried them. The length I have in now gives me about 14 shots at 900-920 fps with 50 grain jsb or Nielsen 50. Max is 960, then goes coil bind after that . I installed one that was one coil longer and actually lost max fps. At 2-1/4 turns in, the current length goes onto coil bind. I think I need to go a bit smaller wire and a little longer length to find it’s full potential. It is bored to .203 valve and barrel currently. I’ll try to find some of the 1.6 mm carbon springs and give that a try… that’s good power in .257 . My efficiency right now is 1.58 with the current set up.
