What exactly is it doing when this happens? I have a shooting buddy who shoots a Tanfo Extreme open gun and changed his major load of HS6 up a couple of grains to get a little more gas to operate the popple holes & comp. The minute he did that he started to have extraction/ejection issues. Went back to his old load and it stopped. So depending on what yours is doing, it can be the load. Mine was always the extractor. The idea of the ejector being bad also happened to me on my DVC open. Had a factory one bend. Bad tempering of the metal and I replaced it myself. The way the ejector is beveled can also change the way it ejects, but not know what exactly is happening to you is hard to figure. Loved the DVC open gun, and eventually got rid of it due to a hand injury and not able to shoot open, went to PCC. But now started back and have a CK Arms Hardcore it it runs great. gerritm

I had a DVC in 38 super and had extraction issues from day one. Tried an Aftec and it got better by playing with the springs and tension, but never solved completely. Went to a Brazos tuned extractor and set the tension pretty tight and it was much better. Never solved it completely. What is it actually doing? Reason I ask is when I had the original full size C-More & factory mount a lot of the times it was extracting OK but hitting the bottom of the mount and stove piping. Could tell by all the marks on the bottom of the mount. Eventually got a crack in the comp & STI took very good care of me on the warrantee work and I had them replace the 38 super slide with a 9mm major. I then replaced the mount with a smaller Everglades mount & an RTS2 dot. Solved it then. They put a stock STI extractor back in it with the new slide and returned the Brazos. I used HS6, 124 PD JHPs, with around 7.7grs. gerritm

We shot many thousand of rounds thru the Taccom 5" shrouded barrel. 99% plated Everglades. Had very acceptable accuracy and never had a lead build up problem in the shroud. Did have a general carbon build up and used the PVC cleaner Tim recommended on a regular basis to keep that to a minimum. Once we started cleaning it regularly we had no issues or problems. gerritm

I have been running mine for 3-4 years with many thousands of rounds. Outlasted at least 1 barrel. gerritm

Then I sealed the cuts with a black paint marker, can use clear finger nail polish. gerritm

Sorry, it was early and hadn't had my first cup of coffee. gerritm

Here is a picture of the 13/16 barrel & CF hand guard with notch. gerritm

Easier to give you the link on Taccom website explaining it with installation instructions. Plenty of pictures. Goes in the upper and clam shell closes against the lower. Not much to take a picture of. Unfortunately they are out of stock, but he gets them in pretty regular. https://taccom3g.com/product/taccom-glock-lower-feedramp/ gerritm

Try a Taccom feed ramp. Best $20 we have spent on our un-supported/non-ramped barrels. Have a JP barrel on mine and installing the feed ramp has stopped all misfeeds,. Had one on her old ULW Taccom barrel before the new one with a built in ramp. Thousands of rounds thru both with the Taccom feed ramps with no issues. Same with the new Taccom barrel with the built in ramp. Cheap easy fix. gerritm

In many 3-gun matches I have never seen this happen, but the questions would be, and only the RO can judge, which is the same as this original post, did the shooter anticipate the beep, false start, reshoot, did the shooter hear another beep, false start, reshoot, or did the shooter randomly fire one into the berm off their hip or shoulder, DQ unsafe gun handling AD, ND, or whatever you want to call it. In 3-gun not sure of the particular rule, but most are outlaw matches with a combination of rules and unsafe, ND, AD, whatever is all enforced in our local matches. No questions. Safety is the most important part of our games, no questions on safety. Looking at UML 3-gun rules, this would be an ND and would be up to the RO to judge the situation. Personally as I said before I would apologize to all and DQ myself if I randomly, took the safety off, put my finger on the trigger, and fired one into the berm before the beep and after make ready and not starting the COF. gerritm

I shoot both UML 2x4 3-gun & USPSA. Other than most of the COF are usually tighter/faster in USPSA with tougher leans, no real problems that I have seen. For USPSA it is good to either have an offset optic or learn to shoot strong & weak hand because the leans are more designed for pistol shooters. Just make sure you know local & USPSA rules for handling your PCC. They are much more restrictive than 3-gun. From un-bagging your PCC at a safe table not at your vehicle. Where to park your cart or bag. Where/when to un-case or take off cart against berm. Waiting for make ready to turn on dot. Several others that you don't always have in 3-gun. gerritm

This. Have run an average of 20K Everglades plated, all weights a year now for 2 or 3 years with no lead build up and consistent accuracy. gerritm

I have TF & MBX. They both work. Biggest thing we have found is to radius the inside of the mag (Glock factory, not sure on others) and smooth out the follower so when the bullets in the extension transition from extension to mag it is smooth. gerritm

Our governor put the Kabash on pretty much all matches in Texas. Can't have more than 10 people at a gathering. Every one in the Houston metro & as far as I can tell across the state are cancelled or postponed. gerritm

3.7grs Titegroup @ 1.125 CCI SPP with 115 plated Everglades bullet. We shoot these in our minor pistols & PCC's. Glock 34, CZ75, & STI 3-gun. gerritm

8.2.3.1 Says that PCC safety must be applied if carbine is loaded after the standby & before the start with finger outside the trigger guard. You all missed my point. Not enough info on what happened to determine false start, unsafe gun handling, DQ or no DQ or what rule to apply. Knowing & seeing thru the RO's eyes that he aimed at a target trying to anticipate the beep off his shoulder or hip is way different than randomly lighting one off his start position. That would be the RO's decision to make. gerritm

I have shot with several guys who either double plug/muffs or are just plain hard of hearing or have amplified muffs and pick up the beep from another bay. Lots of reasons for a false start and have seen it happen. So really would need more info on where the PCC was when it fired. gerritm

Totally confused here and I am noting that I am not a certified RO just a lot of PCC & shooting experience. Not trying to get a shooter DQ'ed if anything we go out of our way to help & warn before unsafe practices happen. No where in the original post does it say that it was at a target. The shooter took the safety off, had finger on trigger and lit one into the back berm, not in the direction of a target. Now my only question would be, was the PCC on his shoulder pointing in the general direction of a target when it was fired, then premature start, no DQ. if it was stock on belt facing downrange, or still at low ready, then unsafe gun handling, Obvious DQ. gerritm

We have been shooting this 1316 barrel for about 6 months & it is awesome. Runs everything. She has a 15" CF handguard and the side ports are just past the end of hand guard & all I did was notch the top CF so the top ports do not blow into the HG. Took me maybe 5 minutes with a die grinder. gerritm

I understand there is no direct rule for this to DQ, but how can it not be unsafe gun handling AD? I have shot PCC in USPSA since day 1 and if I fired off a round after make ready on safe and before the beep, I would A--DQ myself, and B--apologize to my squad for careless handling of a weapon. Whether there is a direct rule or not. Just me I guess. gerritm

Yes, re-shot a couple and it took at least 1 or 2 more tries to fire them. gerritm

Just saw a couple in the Houston area have cancelled. gerritm

I don't believe so. Remember 99% of your shots in USPSA are within 30 yards & most are much closer. 3-gun/UML will go out to 100-120 max usually if you shoot PCC only. Zeroing at 25 yards seems to work and if you can get a consistent group all is good. Have used Winchester SPP with no problems. Depending on your PCC barrel, chamber, magazine, & bullet profile may determine your max OAL, We have shot many different bullets including 100, 124, & 147 grains . Coated, plated, FMJ, & JHPs in testing & matches. These Everglades 115gr plated seem to be as accurate as any and we like the way the dot moves & recoil pulse. Why spend more than you have to. gerritm

If it helps we load all to 1.12 OAL using range brass on a Dillon 650 with CCI SPP. I have a JP 14.5" pinned comp barrel on mine & hers is a Taccom 14.5 pinned comp barrel with built in feed ramp. The 200 yard shot was her shooting offhand with a 6moa red dot so covered the whole target pretty much even turned way down. That is why it took 5 shots or so. She basically held top of the target. gerritm
