I may have to finally try something like that of your friend Pukin Dog, DD. I have hesitated so far because of the chamber mouths of the conversion cylinders. I had measured them some years back (forget the exact numbers) but I recall them coming up pretty much as standard for 38s. I didn't think any .358 bullet would bump up enough upon firing to fill that .375 barrel. But since I can cast a suitable bullet out of pure lead it might be worth my while to try it for convenience sake. Since I am now retired with nothing but time to experiment, I no longer have any excuse!! I just may place an order for that Snakebite mold DD, as I have been pleased with the molds I've gotten from you in the past.
