Well, great minds think alike.
I got a box in from Brownell's yesterday and made it to the range today with my chronograph. Five rounds from my PX4 (4" barrel) averaged 1235 fps with an SD of 7. So it's feistier than the "pretend" version by 60 fps in my gun, about where 115 +P would be (I've never chronoed any, just my guess). POI is the same as 124s for me.
Somebody, maybe SGA, has Independence bulk 115 +P FMJ for $180/k shipped. I don't see this as cost-effective training ammo at the current price. IMO Winchester's 124-grain NATO-spec FMJ is a better choice. This might be a good choice for defensive ammo in NJ where expanding ammo is verboten.
