Someone did not do their homework and it cost some big money. I did not know about that cartridge. I will have to look for load data since it would be a hand load and I dont have any of the old revolvers. I have a lot of 38 spl brass and I was planning on loading 158 grain subsonic for my 357 rifle. That is if the Hearing Act passes. I was thinking of a more efficient cartridge for the load.
