neil, yeah the milpro's also have an alloy insert, and its quite strong and light.
Ive used many different loads in the pt111.
I would recommend Winchester STHP (SilverTipHollowPoint) in 147Gr for PersonalDefence. low flash/recoil, reliable and accurate. the 115gr STHP is an impressive expander, but I usually keep the 147's loaded for a bit more pennetration.
You cant go wrong with the STHP.. hands down...
No fragmentation from the 147, with only a few minor jacket petals from the 115s.. near flawless expansion impacting targets from nearly all angles.. no deflection!
The 115's are for home defence, where I preferr less pennetration!
A cheaper variant, thats also quite impressive, but less costly,(for those of us who like to practice with what we carry) are the Winchester (WhiteBox) USA PersonalProtection 147Gr JHP. These are quite close to the STHP in preformance.. however, upon impacting a target at an angle, they expand less, or un-evenly.. No deflection, however, a bit more fragmentation than the STHP.
for target/range, CCI Blazer 115 FMJ are the cleanest,most accurate, reliable load Ive found.. and quite affordable!
(use the aluminum case, the brass reloadable are much dirtier)
