I'm trying to decide between 115JHP and 147JHP for my next round of 9mm reloads. I've done some 115JHPs in the past, they feed good, shoot good, and I already have the load worked out for them. But, I've been doing some research and some people say 147s are better for self defense. Others say a faster 115 is better and 147s are better for use with suppressors because of the slower speeds (my 115 loads do about 1135fps). What do you think? Should I go with the 115 or 147? Thanks.
