The sheet has 10.0 from a previous pull-down. Just a metering thing?

Its hard to say, I pulled two of these and both were exactly 9.8grs, Power Pistol meters very well.  They could have dialed it back slightly. 

Should I change the sheet to reflect 9.8?


I will start putting the velocity on the sent round bags.

You might could leave it as is or do a second listing in the powder column or a complete line to reflect that loading it if you wish.  He wants me to test with the glock for FTF's, so I'll chrono them while testing.

Well, I got the invoice e-mailed to me on July 18th, 2013, so these are coming up on a year old.  I'd say if your previous measurement was after that date, stick with the previous measurement.  If it was before, maybe stick with mine?

Previous pull-down was March 2013

Failure to feeds in a Glock? What's up with that?

I will just leave it. When PBR gets stock again, I plan on getting some more.

Unfortunately I have FTF...better now since mag spring stretching, though still not solved.  http://10mm-firearms.com/10mm-semi-auto-handguns/g20-gen4-ftf-issues/

Oh okay, received.

I still think you should have Glock replace your magazine springs.

I'm not sure they'll do it.  From their perspective the pistol shot fine when they had it.  I probably will write the guy back after The_Shadow shoots the 50.  If he has no issues, I'm going to wait for another user to get his Wolf 10% magsprings.  If those solve his problem, I'll be writing Glock back asking what can be done about magsprings.  Anyways, back on topic...

Tested the Parabellum Research 165 grain FMJ V-Supreme ammo today, 50 rounds...

My back is still a little sore, it went out last Friday, weather yesterday was horrendous, over 4"+ rain yesterday.  Some of the ranges were closed; however I was able to get into one although it was sopping wet.  Wind was stiff and moving clouds made some shots not register on the CHRONY.

Here are the results of the range trip, Glock 20 SF.
NO failures of any kind.  I did fire 15, 5, 3, 2 from each of two different magazines.

Factory barrel/spring
1290, 1344, 1317, 1340, 1317, 1340, 1280, 1334, 1328, 1191,
1323, 1360, 1380, 1322, 1327, 1324, 1343, 1319, 1331

Factory Barrel Wolff Gun Springs 22lb non captive recoil rod and springs
1295, 1361, 1330, 1335, 1347, 1246, 1342, 1325, 1321, 1333,
1347, 1335, 1328, 1348, 1336, 1333, 1310, 1310

Those were the rounds that registered; I was sort of rushing through this, before anyone else showed up. 

Case expansion was 04330"- 0.4340", typical of Glock Factory Barrels.

No problems with this ammo as tested.   

What's the averages and ES for each?

I didn't retrieve that data, I was having some in the string that were not reading due to varying lighting conditions of fast moving clouds & wind, Front came through again this morning.  Line of weather came through at 3am with some hail and potential for tornadoes.

There was a CWP class that was starting to show up...
