I had a not so great experience with the 240 gr JHP. A less than perfect shot yielded a not so wounded deer. The bullet did not exit after hitting bone. Using my 629 with an 8 3/8 barrel.
I've stepped up to the 300 gr. JSP. Haven't used it yet hunting, but it shoots and groups well. I'm going on the two big holes theory, with no stopping for bone. We'll find out in a couple of weeks
I bought Georgia Arms "Deer Stopper" rounds.
