Remington/UMC 115 gr FMJ is about the softest shooting over the counter
9mm ammo I've tried, as well as being the cheapest around here.
Chrono's just over the 125 pf floor in most full size guns---but it's close.
If you are shooting a major match with chrono, be sure to check it in
YOUR gun---going sub-minor and shooting "for fun" really isn't all that
