Again, reread the thread. I have ensured COAL is appropriate. That is not the issue. Sent from my iPhone using Tapatalk

ID stated it wasn’t a sizing problem. He’s attempting to state it is a COAL problem. It is a sizing problem. It is also impossible to segregate brass to ensure brass is only fired from one gun and lives with that gun. That notion is asinine. Sent from my iPhone using Tapatalk

Not necessarily the case when there are cases that have been fired in about a dozen different guns. Fired cases shot from one pistol don’t necessarily for the next one. Good try though. Sent from my iPhone using Tapatalk

We already know the problem. The problem is in the sizing die. When I pushed the die down where it broke over when the tool head is at full extension, the brass passes the plunk test and the gauge test. However, it has caused some damage to the die as well as made the machine run very rough. Therefore, I will give the Lee a go. I’m also going to run the Redding seating die to possibly low straighter rounds. I’m about 99% sure the existing RCBS carbide sizing die is out of spec. It is very flared at the bottom, and measuring the cases it isn’t sizing down far enough, and each case is hanging up on the same place it seems, just above the rim.

I ordered the Lee U-die yesterday and the Redding seating die, which will perhaps load better ammunition for those heavy coated 147s. Both dies were marked down and there was free shipping and 10% off so was a good time to buy. Thanks for the info guys! Sent from my iPhone using Tapatalk

Thanks for the reply, I don’t think it’s the crimp though that makes a lot of sense. Sent from my iPhone using Tapatalk

Thanks for all the help guys. I’m going to order the Lee die tomorrow I believe. Sent from my iPhone using Tapatalk

Interesting on the comp die. On rifles, the Redding or the Forster dies load straighter bullets with less runout. I had assumed it crossed over here to 9mm. Sent from my iPhone using Tapatalk

Thanks for the info, I won’t bother with it the. Sent from my iPhone using Tapatalk

I’ve been eyeballing the Redding Comp die since even before I got fed up with this issue. I suppose I’ll make a cart on Brownells and wait for the next sale. I plan to get the Mr Bulletfeeder down the road, but want to make this thing run like it should before I add more automation. Sent from my iPhone using Tapatalk

Would taking a few thousands off the sizing die I have provide the same result (as in sizing further down the case)? Are there any negatives to the Lee U die? Shortened brass life? Creating weak spots? Accuracy? I would really like to get to a point where I only have to gauge match ammo and not be a gamble every trip to the range whether I’m going to have a major issue.

I determined my COAL by trying all my chambers and backing down. I am 0.015” off the lands in my shortest chamber. COAL is not the problem. IIRC 1.17” would chamber in all my pistols but one. This COAL works fine in both my P-series CZs and my Scorpion. Perhaps it wouldn’t in a match CZ like the Shadow 2, but it’s excellent in my P07/09. Sent from my iPhone using Tapatalk

After adjusting the RCBS die down 1/8 turn one of the two (of 20) in this last little test would fit the case gauge, but this makes for violent press function. The two pieces of brass plunked, however. Would you recommend a lee sizer over the RCBS? Or any reason not to take a few thou off the bottom of the sizing die? Sent from my iPhone using Tapatalk

Another note, ACME bullets seem to measure 0.001” larger than Hornady or Berry’s Bullets. Sent from my iPhone using Tapatalk

Mont and taco, the only failures to chamber in my guns have been 147 gr Acme. Particularly bullets from my last batch of 5,000. I mostly run 147s in my CZs, Sigs, and HKs. I’m on my second lot of ACME bullets and trying to universalize my ammo for all my guns. I had switched bullets back and forth before while my supply of 124 FMJs and plated bullets dwindled. Usually, in the Glocks and my VP9 I shoot 124s, some Hornady FMJs and some Berry’s plated bullets. I can’t think of any times I’ve had a failure to go into battery with Berry’s or Hornady 124s. I have had them fail the case gauge, but pass the plunk test. Perhaps you guys are on to something with it being the coated 147s being an issue of either seating crooked or being slightly over size causing certain brands of brass to be too thick, once a bullet is seated. I’ll go back and do some measuring. Perhaps they need more of a bell from the expander? Would a competition-style seating die perhaps correct this? I really hate to spend money, because every $100 I spend chasing it means more than 1,000 rounds of ammo I can’t make. At this point I think I can file or grind a couple thou off my RCBS sizing die to get the press running smoothly again and it does appear maybe 1/20 doesn’t get sized far enough...but that doesn’t seem to be what’s causing problems with the rounds that don’t chamber on the gun.

I ran 20 cases through just the sizer. Two didn’t fit the case gauge. I ran the size 1/8th turn in past the break-over of the ram and ran those two cases through. One case dropped into the case gauge freely. The other case did not. I took some measurements. The case that did not pass though the gauge was 0.001” wider toward the rim. All cases passed the plunk test on my loosest chamber...the Glock. However, this depth on the seating die is similar to what I ran before and runs very rough and actually damaged the end of the die. Powder commonly splashed out of the charged cases before reaching the seating station. Perhaps a new seating die is in order? Or perhaps stoning 0.001-0.002” off the current die? Another observation: all brass failing the case gauge and initially the plunk test were R-P, Winchester, and Federal stamps. The Aquila, Blazer, and Speer have had zero rejects. With the exception of Speer, the failed brass were stamps all shot through the Glock on the first firing. I’ve read over and over that 9mm Glocks don’t typically have an issue...but it does seem this chamber is very, umm, generous? Sent from my iPhone using Tapatalk

I’ve been reloading for 16 years or so. I’m only new to 9mm, but I’ve loaded precision rifle, hunting rifle, and so on rather extensively and successfully. For handguns, I’ve loaded quite a bit of .45 ACP and .44 Remington Magnum. The sizing did won’t go any further. As I said before, I tried turning it in an eighth turn into the shell plate and it wore/damaged the bottom of the carbide sizing die. My first impression is that IS a sizing problem, but I found it somewhat hard to believe that RCBS would design a die that physically won’t accomplish the task. I will try to run ten cases or so real quick and see what happens. Sent from my iPhone using Tapatalk

Hello all. I’m having an issue with rounds failing both the case gauge and the plunk test on a variety of pistols. Typically, many rounds pass, but perhaps about one in ten fails. I use a Hornady LnL AP, RCBS carbide dies, a Lee Factory Crimp Dies, mixed 1x fired brass, CCI small pistol primers, VV N320, and ACME 147 gr flat nose bullets to an OAL of 1.15”. My seating die is adjusted to just kissing the shell plate. I have tried it 1/8 turn into the shell plate and it just wore the base of the die. I’ve tried only leaving enough bell to barely allow the bullet to make its way into the mouth. I have the searing die backed off enough that the seat/crimp function is disabled in favor of the Lee factory crimp die. I’ve also run the Lee FCD all the way in. No matter what, the issue persists. For the life of me I cannot find what the issue is. Brass will gauge or plunk to all hit the last 0.125” or so of the case. I’ve tried running magic marker coated brass through to see where the failure is. It almost seems most of the cases randomly bulge 3/4 of the way toward the rim. Currently the brass is being shot in CZ, Glocks, VP9s, and Sigs. Occasionally I’ll end up with failure I go into battery on rounds that slip through when I don’t gauge every single round. Sometimes it’s too tight to rack the slide to get the gun back into operation and requires breaking the gun down. At at this point, I’m considering replacing the dies one at a time to see if that makes a difference. Please, what am I overlooking? I’m about to the point where I’m just going to give up reloading 9mm if I have to check every round...it’s hust not worth that kind of time investment for anything but match ammo. Thanks I’m advance!

I’ve not run Tangfos, but other DA/SA guns do this when the trigger return spring is bad. Sent from my iPhone using Tapatalk

Google “USPSA production list”. I believe there is an addendum that states factory threaded barrel versions are legal. Sent from my iPhone using Tapatalk

At the danger of drifting the thread, do the Glock “dryfire mags serve any purpose or do reloads eliminate their usefulness? Sent from my iPhone using Tapatalk

I do currently reload. But upgrading to a Dillon and possibly a Mark 7 should save me time, which is a commodity for me. I wouldn’t mind buying large lots of components at some point. Sent from my iPhone using Tapatalk

I would consume what you consume on a regular day. If you pump caffeine most days and don’t on match day, you’re going to have a bad time. Sent from my iPhone using Tapatalk

Good info, thank you. The money I was going to slowly devote to a CZ I just may spend on a Dillon and reloading components/gear and perhaps a class with a GM. Sent from my iPhone using Tapatalk
