Too much Lemishine will react negatively with the zinc alloy in the brass casing. It causes a chemical detrimental reaction with the zinc in the brass. You will literally weaken the strength of your brass casings if you use too much of that product. The "pink" color you see on the brass is a teltale sign of chemical damage to your casings. I use one teaspoon of that product per one gallon of distilled water. I wouldn't use more than that.

I would suggest removing and cleaning your barrel. Then coat your loaded round with black felt pen or Dykem. Drop that loaded round into the chamber and see where it's htting in the chamber. Shiny spots appear on the loaded round in all the tight areas where the round hits the inside of the barrel chamber or rifling. I had that same issue a while back.

I've been experimenting with 9X23 brass shortened to 9mm Parabellum. It's far more durable and definitely withstands the 9X19 major powerfactor requirement and produces far less case bulging and splitting issues. I also tried modified rare 9X25 brass that I bought cheap at a garage sale, and that stuff is also extremely tough, even when over-charged.

I don't use those horrible Blue bullets anymore. They are inaccurate in my guns, over-priced, and they lead up my PCC comps terribly. And as a personal health side note - I don't like using a coated bullet product that contains PTFE Dupont® Teflon in it, which when exposed to a super hot burning powder charge, emits known carcinogenic toxic particulates into the atmosphere that people breathe from the muzzle smoke, especially in my local indoor public range where there is little to no ventilation. As someone else already stated, there is a proven good reason why governments banned Teflon coatings for use on food preparation cookwares.

I can tell you for a fact that as a general rule the longest possible OAL will make for more accurate group size and lower cartridge pressures, which in turn saves brass life, and will also allow larger powder charge weights. A longer OAL will also contribute to cleaner chamber throats when using coated bullets in pistols in extended shooting sessions.

Not really a "blanket statement" but more of a general rule on OAL.

I think that's a bit drastic and malicious to ban a shooter for that. Those kinds of people should be required to attend and show proof of professional firearms training before attending future participation at any public shooting event My neighbor is a police officer who shoots on his own property and doesn't even exude the brain power and common sense to keep his bullet projectiles on his own property instead of into the side of my house and through my parked vehicles. And that incompetent idiot carries a loaded firearm in public and has the powers to arrest and kill someone if required to.

Seating depth has a HUGE affect on group size. I found that out by simple experimentation. You wana go as long as possible at all times.

I just got 40 lbs of 1945 era military surplus pistol powder so I can run 125gr J-Ames bullets. Best weight for accuracy from what I can afford and super clean in my PCC. One hole drillers in my Glocks and Leadstar PCC's. I would buy their 147 rnfp ones that are even more accurate but I can't afford the higher priced ones. I got lucky and bought two months ago when they had more for everyone. It appears they cranked up mass production lately but mostly only to law enforcement agency contracts and most of their bullets go there, and less go to civilians is what I'm hearing at the range.

Too bad they stopped making/selling delrin horseshoe locking extended base pads to go with their springs

I just can' believe people actually buy those. I should've done my homework before buying one. Even 22 plinkster was not happy with that gun, Bad reviews - and for good reason too. They just don't run ammo well. And that what appears to be homeland china manufactured cheaply made top end slide...don't get me started.....

I don't like em. They remind me of the old para tube parts from brownell's that I think metgar made. Lips are too flimsy and distort easily. You have to have a lip forming tool to reshape them. God forbid you drop one in a three gun match.....you'll be so pissed

Been thinking about that same thing myself since I got into shooting. I went to their website and started drooling ...quite pricey tho...

It sounds like you may have debris caught under the extractor or your rounds have a low powerfactor.

I see old farts doing it pretty regular
