I shot about 20 hardcasts. It went well, accurate and a little softer recoil.

Afterwards, I ran a mesh lead cleaning plug (Lewis lead remover) through the barrel.

This is what it looks like at first pass. Wow!
The 10 Ring

Since PowerBond is selling the plated .401 bullets (at $67 per 500) but not putting a speed limit on it (Berry does) and I tested them at 1,350fps with no tumbling and very good accuracy, I think I'm done with lead bullet for now. I also use their 9mm product and saw no difference compared to true jacketed bullets.

I'll keep my remaining Lead stock to the easier to clean 6" barrel.

Now you know why Glock doesn't want people shooting unjacked lead out of their barrels.

That is a lot of lead. What size were your boolets? Mine are a hair under .402 that I have been shooting.

Makes sense! If a slug comes down the barrel while a lot of lead sticking to the wall, it can plug up the (previously) .400" (?) hole real fast ... then the pressure has no where to go but burst the barrel. Medically, it's probably equivalent to cholesterol and a stroke.

Advertised as .401 but I should measure a few to check.

Not really. With a stroke the cholesterol breaks free from a place like your arm and then travels through the arteries and up into the brain. Arteries flowing outward toward the brain get smaller and smaller... eventually whatever breaks free from the artery wall gets to a choke point and blocks the blood flow and starves the brain from oxygen, etc., causing a "stroke". The more that is starved from blood flow, the more that gets damaged... and so the worse the stroke.

.4015 is what I found to be min size for my ccu. The ones I am shooting now are .4018. .402 worked but were tighter in the chamber than I wanted.

Try the next size bigger on the bullets. Your cast bullet needs to be at LEAST .001" over groove diameter. For my longslide, that is .401-.4105" at LEAST... For my .44 revolver, that's actually around .431-.432" as I've slugged my barrel measurements. Bullet FIT is the best way to prevent leading.

Thx. To be fair, 16" is a lot of barrel (vs. a 4.6" barrel) to deposit lead on.

Update: after some 500+ rounds, the CCU is a solid performer. I discovered a couple of things.

1. GlockBlock modification that I showed earlier was LESS reliable (may be 90%) than the OEM (99.9%). In an earlier post, I mentioned that instead of taking away metal to make the groove we'd need to deposit metal. It seems the OEM part, even though flat, bounced the bullet sufficiently early to the chamber to feed it whereas my grooved one was marginally late. Marginally late feeding action jams up the bullet prior to chamber entry. It also depends on bullet profile, round vs. conical. A work-around for this issue is to do 1.260" OAL instead of 1.250", but then you'd be doing a different reloading just for the CCU. In other words, you'd want the bullet to bounce into the chamber early, rather than later. Long cartridge bounces into chamber more reliably.

2. The back end of the firing pin has a retaining washer, spring, and a washer clip. They get bounced into the plastic recoil absorber pad along with the bolt. They can come off, a minor design weakness. I just JBWelded the clip since the whole firing pin assembly isn't meant to be taken down anyway.

Other than those issues, one is mine and the other is minor, the MTech feels smoother every time at the range. I warn you. Unless you reload to alleviate some ammo cost, it's far too easy to pull the trigger just because "you can" particularly when you have a 30 round mag!

A lot of fun in shooting... Accurate enough... I can pick off small fragments of orange clay disks that had already been shot by another shooter at 25 yards, free hand.

A little padding on the m4 stock butt will help the enjoyment.

I think o. the block u just may have just gone too deep. Mine is only half as deep as yours and mine is flawless. I have not looked be that clip on mine. I should peek at it.

I think so. It actually worked fine with conical bullet. It failed on some round nose hollow points that has different ogive profile. In any case, we now have a record of how deep is too much.

Try cut and paste your picture on the post, so I can see yours. Get a free acct on photobucket. Upload it there. Then display it in that window. Right click, and chose COPY. It's now in computer memory. Now goto post your comment on GT. right click and PASTE. That's all. Just make sure your pics are 640x480 or smaller, before uploading to photobucket.

I am a cheap skate. I got a Lee LoadMaster 10mm. It was around $200 with all the trimmings. The design has a lot of negative reviews on primer feeding aspect of it. Read all the complaints, diagnose the basic flaw, then fixed it. I just polished the heck out of it, primer feeding tracks and all levers. It works beautifully for me, pumping out some 400+ rounds an hour. The only annoying part is that I had the stop to supply more primers or cases. 400 lever pulls = 400 rounds.

I guess I can go faster if I buy more primer dispensers and preload them.

It's good enough for the MechTech CCU.

Who wants good enough?
The Hornady AP LNL press I have now is "good enough"
Im young, single and have money to burn dammit!

Also, I just wanted to post a video of the awesomeness

I cant wait to load up some 125gr Tac XP bullets and see how fast I can get them going!
I wonder if 2000fps is possible with that LOOONG bullet

I would bet 2000 is able to be hit. If I an get 180 to about 1800 a 125 should do it no prob even with the length.

Side note from today. I was shooting a few of new loads and I did them with a med crimp. Big mistake. I set back 6 in a row enough that the case mouth was exposed. Only use firm heavy crimp with the mech tech.

So I have a new improvment to add to the block. Get some thin rubber. Uses weather strip adhesive. Glue it to the underside of the block that sets on the locking block in the glock. Only needs to be thin. It holds the block tight against the barrel in the ccu. Makes it even feed better. Very smooth. Very simple and the magnetic block still sticks from the magnet. And holds a little extra from the rubber. Will have to post pics.

Testing it I put paper under the block to raise it up a lil. Just to test. Was way impressed. Then filled it with jb weld. Thin layer. Worked well. Then I did the extra block I have with the rubber and really liked that. When you slide the frame on u will feel the block slide against the barrel for a super tight feed ramp fit.

A "new improvement" for yours. If you read my post a ways back, you'll notice that i used basically the same adhesive on mine... except i did it about 10 years ago............ or so.....
