  1. Brass expands in the chamber at the moment of firing thus sealing the chamber, it actually starts to shrink once the chamber pressure starts falling and extraction is begining. If you are fimiliar with the HK model 93 the brass comes out stripped down its length from the chamber being fluted. this helps it break the seal of the brass to the chamber, which is to say that brass sealed to the chamber causes a few micro seconds of friction before ejection. When you oil the brass before firing you are causing more stress to the action because the forces in the chamber put more thrust on th
  2. I may have missed something, are these the facts? . at 25 yards and full windage adjustment on your front sight plus a kentucky windage of holding to the right by using the left edge of your front sight you are now centered for windage? If that is what you had to do your rifle has a problem. the trinion fit is off or something else not alinged during its manufacturing. take it back to the dealer who will send it back to the distributor and he will send you a new one. The less that you mess with it the better, Be sure that you don't leave any marks on it trying to fix it yourself. A r
  3. Nice test. Why would anyone want a saiga when you could have an AR that has A buffer system in the plastic stock. Just a good dent in the buffer tube will will put an AR out of action, much less when a vehicle runs over the stock. But then they do make all of those neat gadgets to bolt on AR's. What happens to them when they are dropped?
  4. I am just A newbe to this forum, but i cannot keep my mouth shut about 1911's. First see the feed ramp on the last picture of the kaboom HK, As in most moderan designs the feed ramp is extended well past and below the chamber. This gives the round a much better chance of chambering thus more reliability, Also If throating is required (this is unusual in a extended ramp gun) it would not necessarly remove any of the chamber support of the round as it can in 1911's. So I will admitt that modern pistols with extended ramps may be more reliable and less likely to kaboom than that old gu
  5. Sure I may not seem too up to date, But someone needs to include the 1911 more. The kabooms that Ive seen in them has always blown the magazine out and sometimes splinered the wooden grips, but no structual damage. Usually they blow the brass just in front of the case head due to someone reworking the feed ramp too much. The dremel tool is the enemy of the 1911. I own several accarate and super relialable 1911's this is the result of owning many 1911's through the years and never keeping the ones that didn't measure up with just minor tuning. I would never guarantee the next one to be g
