  1. We fired ~60 rounds of mixed brass. The Tula were the only ones that did this. If it was Starline brass bulging like this might blame the gun. I'm calling this thin cases in a fast cycling delayed blowback.

    This upper has ~350 rounds through it in total. No other fired cases bulged like this, well none I was able to find.

    Based on my experience those cases will probably rupture on the next firing despite roll sizing. My guess the brass is weakened beyond repair after going that far out of spec.

    That was sarcasm. They are going in the recycle bucket.

  3. Was shooting some of my practice loads from our suppressed Banshee with the wife the other day. Didn't bother to pick up the brass until today and look what I found. These were mixed brass, 147gr MGB @ 135PF loads. Only the Tula brass did this.

     

    Roll sizing should fix it right up.

     

    I'll report back if any other brands of brass behave this way.

    The Banshee upper has run damn near 100% so far. Nice to be able to slap an upper on any standard AR lower and have it actually work properly out of the box with no mucking about.

    What is the T-Track?

    I used the "Heavy Duty 7/8" Wide that takes 3/8" bolts. If I did it again I think the thinner standard 1/4" bolt head stuff would be fine. The mounting holes on the Dillon Strong Mount for my 650 & 550 and also my MEC9000H mounts are 9" on center so they can be bolted down easy. Since I'm using 3/8" bolts I did have to enlarge the mounting holes to 3/8" on all of them. I'm guessing the 1/4" holes in the mounts should have been a clue to me. Oh well, lesson passed on. The Mark 7 1050 I use for small primer stuff comes on it's own base so I can move it whenever my back feels up to it.:-) Still need to make mounting plates for the RCBS presses, the 1050 setup for Large Rifle and various accessories like the Giraud trimmer. I'm building two more benches more or less the same as this one, just taller. This bench is only 30" tall, otherwise I would need a step ladder to fill the bullet and case feeders. The other benches will be 36" tall. 

    When I looked up info on using T-Track for a loading bench I found very little useful information. It does not seem like much but just these couple of paragraphs represent hours of research. I hope it helps someone out.

  5. Moved from CA to ID and am finally getting around to my reloading / man room. Feels good to get the first presses set. I used old fire rated doors from the local Habitat for Humanity for counter tops and set 7/8" Heavy Duty T-Track into them.  The T-Track is 9" on center and works perfectly with the Dillon Strong Mounts. The RCBS, MEC etc. will be on 11"x whatever mounting plates made from 3/4" plywood. Ahh . . .  progress.

  6. My 7000Pro worked just fine with the occasional reset, like twice in the last two years. I keep it in the little rubber protector they sell and try not to bang it around too bad. In the last month or so it started for no discernible reason illuminate the buttons, and nothing else and become unresponsive. It stays like that until the battery dies or I take it apart and pull the battery, which is a pain in the butt. Takes a day or two on a full charge for the battery to run down in the buttons lit, failed state. It takes a really small screwdriver to take the cover off, smaller than what I normally carry in my range bag I found out the hard way when it first started acting up.

    With CED dropping support for the 7000Pro after such a short (compared other shot timers) product life I'm guessing these are not the most reliable electronic devices.

    One of the local clubs uses the standard 7000 and I've not heard anyone complain about them.

    Should have kept my PACT C3.

  7. I've found after going back and forth between many powders for 147g loads the best so far have been N320 and what seems to be it's brother from another mother, Ramshot Competition. I've shot endless rounds over the chrono with sorted brass and Hornady HAP and MGB TMJ 147g bullets. 3.2 to 3.5 grains of both of these powders produce almost identical velocities and felt recoil.Primers don't seem to matter much, 20fps at the extreme. OAL is 1.145" or less since we shoot it out of several CZ's.

    3.5g of Bullseye works well also, not quite as smooth.

  8. That is pretty sweet, ran mine for the first time at a match last Saturday. What sights were you running?

    Green fiber front, stock rear with the dots blacked out.

    Thanks! What FO front sight worked for you?

    I think it's a Tru-Glo. Honestly I forgot.

  9. Since CZ's are make from Czech steel you need to lube them with products from the Czech Republic. All the US made lube you fools are using will never work on Czech steel.

  10. There is also a health consideration with all the dust created when using the dry method.

    Yup, I'm 46 and have been casting bullets and reloading since I was EIGHT. My blood lead level is completely normal.

    Wash your hands.

    Put a couple of used dryer sheets in your tumblers.

    Close the lid on the tumblers, no perforated lids.

    A tablespoon of Mineral Spirits in each tumbler load also cuts down on the dust, but is not required.

    Wash your hands.

  11. You don't need to use liquid to clean brass, especially in a cement mixer. The entire process of adding in liquid adds considerable time and a bit of cost to a process that simply does not require it.

    Plain old walnut shell from the feed store in 50lb bags along with a small amount of mineral spirits or your favorite brass cleaner (Dillon or Flitz) and toss in a couple of used dryer sheets to cut down on the dust. Simple as that.

    The cost of liquid (dawn is real cheap, lemishine if desired is cheap per load and water is really cheap) is less than the cost of the walnut shells, mineral spirits and polish.

    I like to wash brass, well before I used stainless steel media tumbling I used to wash my brass in water and dawn in a tub with some hand agitation (pretty high tech). Those results alone were pretty good and one could have easily loaded the brass after that process. Washing the brass is more effective for some of the brass I pick up as a result of the amount of grit, sand and small stones that find its way into the brass.

    My drying technique is pretty expensive too, I let the brass air dry...

    You are using a cleaning technique intended for benchrest shooting with extensive brass prep investment on pistol brass churned out by the thousands. Are you depriming your pistol brass before you clean it? If you are there is one more brass handling step most people don't have. If you are not de-priming then at some point you will have water contamination in your primer pockets. It's just a matter of time.

    Using any liquid cleaning method on pistol brass, or rifle brass for intended for blasting ammo is a complete waste of time and effort. If you have time to burn, knock yourself out, I've got better things to do with my life than fuss over how shiny my brass is.

    Who said I was doing just pistol brass? My "brass prep investment", particularly with pistol, is not "extensive" or expensive. No matter what method you use, it takes some effort unless someone else does it for you. I let machines do most of the work for me these days.

    You have made your opinion clear, but your comparisons and observations aren't always accurate (cost, time, etc.)

    What have I said that is not accurate? My opinion was earned the hard way, by trying all of these methods.

    Wet, dry.

    Removing primers, leaving them in place.

    Commercial walnut media, feed store crushed walnut.

    Commercial corn cob, feed store corn cob.

    Stainless steel pins, ceramic pins.

    Various commercial and home brew wet solutions.

    Vibratory tumblers, rotary tumblers, cement mixers, sonic tanks.

    Flitz, Dillon, car polish, mineral spirits

    Clean your brass whatever way floats your boat. I'm just trying to save the newbs from being dragged into time wasting OCD insanity.
