Special Snowflake Glock Part Deux

G32 with seemingly ubiquitous PHLster and UpLULA

Went to MCF&G yesterday morning to do some chrono work in the pistol bays. This project was interrupted by the need to leave the range and get a fresh 9-volt for the chrono, but fortunately someone was shooting in the next bay over and agreed to keep an eye on my chrono setup while I ran down the road for a Duracell.

I brought along a twenty-round box of Hornady Critical Duty 135gr FlexLock and a fifty-round box of Winchester RA357B 125gr Ranger Bonded hollow points.

The gun still showed that it liked a strong grip, as the slide didn't trickle all the way back into battery after firing one of the Rangers. If this is a persistent problem, I'm going to talk to smarter people and see what they say about going to a stronger recoil spring.

Ballistics, in case you don't want to decipher my chicken scratch in the picture:

Hornady Critical Duty 135gr
LO: 1176
HI: 1202
AV: 1186
ES: 26.28
SD: 8.66

Winchester RA357SB 125gr Ranger Bonded
LO: 1308
HI: 1379
AV: 1348
ES: 71.00
SD: 23.49

Note that, once again, Hornady delivers amazingly consistent numbers. That 8.66fps Standard Deviation is match-grade in anybody's book. Interestingly, Winchester claims 1350fps for this load from a 4.00" test barrel, and I observed 1348 from a 4.00" gun. This was a novelty to me.

If anybody's still turned on by energy numbers, that's 422 foot-pounds for the Critical Duty and 504 for the Ranger.

So, that makes 169 total rounds fired with three failures to go completely into battery (#63, #78, #126). 1,831 rounds left to go.
