  1. Uhh, no. It's a reinforcing stamping that is not an indexing location. This has never been a problem since the stamping is not needed for the hole and the hole is not needed for the stamping.
  2. A few things. First shells come in different lengths, you have 2 3/4" and 3", the 20ga saiga uses two lengths of magazine to handle this. Most common shells are 2 3/4 and you can get defensive and hunting grade buck and slugs in 2 3/4" so 3" are not super necessary. Then there are two styles of crimp, roll crimp which is longer, and star crimps or fold crimps which are more common. The length of the brass does not change the length of the shell.
  3. 2013 ammo production was very dodgy stuff.. My own homemade reloads from 2009 are better than most of the factory bulk pack stuff in 2013. I had some federal that was not sized right and the metal bases would not seat in anything, not even a double barrel, ended up having to run it through my reloading sizer to use it, a little dangerous to size live ammo but nothing exploded. My new policy on ammo buying, buy it when it's not made in a rush.. I loaded up pretty heavy from 2015 to the end of 2019. When the panic buying started I stopped buying pretty much everything. The QC on everything
  4. My suggestion. Promag, caliper and a file.. Figure out what the difference is and make them the same. ALWAYS measure relative to the AMMO. Goal is ammo into gun, as long as the ammo is in the same position in the gun, the shape of the outside of the magazine is totally irrelevant. So if you are lining two magazines up, load a few rounds into the magazines and use the lock up points to compare.
  5. Yeah probably for the best. Nothing stopping me from the MKA-1919 and clones, except for a HUGE lack of consistency with the guns. I can't afford to fix that mess.. There are products we have walked away from because the original makers botched their quality control to the point that it is too costly to fix the problems, people have this idea that shipping stuff back and forth is cheap, how much profit is left shipping a $40 item back and forth a few times at $11.95 per trip? Nothing. I can and do make stuff that is not for guns. I like making gun parts, it's fun. But I'd rather weld
  6. It's actually half mass x velocity square. https://www.calculatorsoup.com/calculators/physics/kinetic.php But yeah either is better than high brass low brass. And I'm amused by black aces abandoning their magazine production. We offered to make them under some sort of mutually beneficial agreement. But they wanted to make money on the magazines. They patent locked their magazines by making the gun use a feature they had a patent on. Same for the remington box mag guns. Current patents are 20 years I think. So I can make replacements for the black aces gun in 2034 and the Re
  7. How about a snap cap? Load a snap cap as your top round, triple confirm it, then chamber the snap cap, when you go to fire the snap cap is ejected and the fresh round loaded.
  8. with Russian guns a file is your friend. It's not that complicated, but these are not AR-15s. Most parts require fitting.
  9. Yeah you need to add some metal to the safety to get it to engage.. It is not a hard job, I did mine in like 15 minutes but not everyone has a welder.
  10. I think we just ran out of the second batch, we are in the process of making more.
  11. Maybe use an empty shell filled with a dowel rod?
  12. Most shops use a bullet trap for test firing.. I have a small 10 yard indoor range (underground) which doubles as a hurricane shelter. Only issue is that it is a pain to decontaminate before storms, it takes a whole day, and another half a day to process the water used for cleaning.. If I was a gunsmith I'd probably do a small shipping container with a bullet trap and sound insulation, and a very large multi stage hepa filter on the exhaust. One thing with a home range is that if possible your bullet impacts should have something above them, that way any glances will hit something, like t
  13. Get some rounds down range.. Either you will find a use for it or you won't.. Mine gets used for grouse hunting in swamps from time to time.. And it went out for a couple hog hunts on an air boat.. Otherwise it is a range toy.. I normally use 5 round magazines with mine.. Five rounds is more than you can realistically use hunting, because all game animals are long gone by then. At the range I'll use the 10s or 20 round drum.. For home defense, I can't see anyone sticking around for 6-10 rounds of buckshot.. They are either dead or running away by round five... But my home defense is
  14. 922R was primarily made for importers and manufacturers.. And I would point out that no one is checking this stuff since the law would most likely get struck down in court for several reasons.. So really nothing to worry about.. The 922R information is kinda dated and in my opinion was overblown to sell "compliance parts" But just for the heck of it, let's imagine we care about 922r: It's normally stated that the Saiga-12 has 15 counted parts, goal is 10 or less imported counted parts.. Three are in the magazine, one is in the stock, I think that stock is USA made, odds a
