Observations about longer barrel, etc.
1. The 5.15" LW barrel makes more of a velocity difference than I thought it would. With 4 different identical loads, velocities are almost 100FPS higher.
2. This LW 5.15" barrel is also the mostaccurate I've had in any of my Glocks. For instance, today's 20 5shot groups averaged 3/10inch smaller than the essentially same loads shot over the weekend thru the original barrel.
3. After a little preliminary velocity measuring Tuesday nite, the groups I shot today were strings with lower charges of Longshot and A7 and 4 loads of A9 creeping up to what I thought I wanted. Turns out 3 loads1 with A7 and 2 with A9of the 9 loads I shot had tooHIGH velocity for my desires for a 155g. PD load. Some may, but I don't need a PD load generating 10' velocites over 1375FPS, but it's sure a nice problem to have.
4. Based on ONE batch of 18 groups from 9 different loads, so far the loads with A9 are generating the smallest groups, but that's only by a tenth of an inch at 10 yards.
I sure am liking this.
