I bought a model 37 in 1978 and have been working on a load ever since. It is a most difficult gun to "practice with what you carry". I finally settled on 158 gr. (for POI=POA) and full meplat. Shown below in .38, .357 and 44 versions. The loading is the same as a 158 SWC so you can adjust from there. I could tolerate hollow point expansion velocity in my model 36 and 60 but never in the 37. (molds by Accurate)
