  1. He constantly practices and wants to make a career of it, so he definitely does the work. Sometimes he would stay at my place while we developed the weapons systems and test/develop at my private range. He is definitely fast with that shotgun. Jack
  2. Thanks guys, appreciate it!!!! Got my prosthesis today after being on crutches for a year, what a difference. Will take some time to get use to it, but I will be back in competition in about 6 weeks!! Jack
  3. I built his Saiga 12, his original VEPR and his first Open Competition Pistol. The pistol was much more modified than the shotgun as it has to be controlled by his nubs, I had to design special safeties, mag release, etc. so he could manipulate the firearm.

    Muzzle Brakes

    No individual can possibly say what the best muzzle brake out there is. Recoil is perceived by each individual. Also, what feels good one day, might feel like shit the next because you are mentally/physically not into the gun. Also, you may weigh 350 lbs and what works for you won't work for a 160 lb guy. What works on a stock gas block shotgun is having some weight on the end and just as importantly have the shotgun properly tuned to the shells you are shooting. Basic physics, more weight equal less felt recoil. Gotta find a balance that works for you and if you like it and you t
  5. No sense in getting a 20 if you can find a 12. A 20 gauge is basically 7/8 oz shot at 1450 fps. Exact same as the 12 gauge international load. This is what I set up Kay Michulek's shotgun for when I originally built it for her. But of course you can can run a more conventional 1 1/8 oz 1250-1300 fps load if you are going to shoot outlaw competition where the steel might not be calibrated to a 9mm minor to fall. Plus you will need a choke on the 20. Gottal keep a pretty tight pattern if you are going to shoot competition and knock down steel with any authority. Dont waste your tim
  6. We're good man!!! My "Back Room" comment is in regards to how the dis-information is passed from one person to another like at a range, gun shop or a bar. It really doesn't matter how we try and help, it seems like someone always gets their feelings hurt, like "Gun Fun" because he thought we were taking about him. What J. Lambert and I were referring to was not even on this particular topic. But it is true. Gun Fun proved that!!! There was nothing condescending about my post, unless you think it is directed at you (Gun Fun). And it doesn't matter how nice or professional we try
  7. I was supporting your definition of "Dwell Time". The evlblkwpnz guy was putting out erroneous information. So now I am going to hurt his feelings and he can write a nasty post to me:) Jack
  8. I am sorry if we hurt your feelings, maybe you need a big forum hug?? Jack
  9. No way!!!! You don't need any tools to completely strip, and I mean completely strip a 1911 and there are not very many parts. How many parts are in an M9 and you can not completely strip an M9 (average guy) in the field, remove every pin, spring, etc. Compare a 1911 and an M9 Parts Diagram and there is a huge difference!!!! But there again, I grew up with the 1911 and can completely disassemble one (field strip) blindfolded and not drop any parts in about 10 seconds.. An M9 has about 3X the parts of a 1911 so how can it be easier to maintain? Jack
  10. Yeah, but we tend to get slammed by the guys who just built their first Saiga and now they consider themselves Master Gunsmiths and know it all:) Jack
  11. I've never served, so someone please correct me if my thinking is all wrong, but if you're down to your pistol in a combat situation you essentially don't have a gun and may as well start hurling insults and rocks, right? Soo... Since it is probably YOUR life on the line. in a very hail mary moment, just why in the hell can't you carry whatever you want as long as it meets a minimum standard and you pay to own/maintain it? Obviously the military couldn't support 800 different pistol calibers, but if you want a Hi Point 9mm or a $5000 target 9mm, why not? Cops can do this in many jurisd
  12. We didn't want to get rid of the 1911's for this very reason!! I was working at Mott Lake (Fort Bragg) Special Operation/Counter Terrorism Unit at the time they decided to get rid of the .45s. Numerous write ups had been submitted to allow various units to retain the .45 for several reasons, it causes more arterial damage and temporary wound cavitation damage than a 9mm thus having a higher percentage of putting the aggressor down with one shot. AND the .45 wasn't as likely to penetrate walls, etc causing collateral damage which a high velocity 9mm will. It was politics as usual, th
  13. Here is the definition of "Dwell Time" which has been used in the firearms industry for a long, long time: In a gas-operated automatic or semi-automatic firearm, the dwell time is the amount of time that the gas system is charged with high pressure. It is determined by the amount of barrel after the gas port; once the bullet passes the gas port, the amount of time it takes to get from the gas port to the muzzle is the amount of time the gas system is charged with high enough pressure to cycle the weapon. Here is one of the links that has this definition, there are many more: http://gu
  14. The muzzle device may be pinned just as easily as the gas blocks are:) The barrel has a little bit more diameter/wall thickness at the gas block, but it is not a problem and no big deal as long as you have enough wall thickness on the muzzle brake. Need to have a vertical mill or a good heavy duty drill press with a compound table/vise to do it professionally and without fucking it up. Jack
  15. Take a hard look at the Dillon 550, as it is very cost effective and you can build up multiple tool heads to cover just about every cartridge out there. I have two of them along with two Dillon 1050's and one of their Dillon Square Deals, which I take with me when I travel, as it is easy to set up in a motel room and load pistol ammunition. For precision Rifle I use the Redding T-7 Turret Press, which is a single stage press, but you can put seven dies in the rotating head. It is rock fucking solid!!!!!! Really comes down to how much money do you want to spend!! Jack
