The +P+ designation means "loaded to no SAAMI standard".
It does not automatically mean loaded to any certain pressure (as some +P+ ammo was loaded to lower-than +P or standard pressure); it means no standard met.
Just like CIP pressures may be higher than SAAMI, some may be lower.
Someone else wisely mentioned, skip hot ammo, get a bigger gun (coughs in
GrayArea ).
yes my 115g JHP load goes 1420fps
