Hey Guys, just wanted to share what happened to me at the range this weekend. I shoot in speed steel competition, shooting six steel plates in various positions as fast as you can. I shoot a Sig P226 Scoprion 9mm with 3.0g of 700x and 115g Extreme bullet. In the middle of a match, first and second shot went off fine, third shot I saw my front sight dip, no sound, did not cycle, so I racked another one in (assuming the primer did not go off) and shot the fourth. It hit the steel plate but did not cycle. I went to rack it again and the gun was jambed. I MEAN JAMBED!!!! I could drop the hammer, so I got my flash light and looked down the barrel and I could see the empty case. Then I noticed the barrel was split. The third round only went half way down the barrel, the next round knocked them both out and hit the steel plate and split the barrel. The R.O. next to me said he never heard the round go off, like you would if you only had a prime in and no powder. I never heard it or felt it. A few weeks ago we had a 45acp go off with just a primer and with would not cycle the next round in the chamber because it barely went into the barrel. It took me three hours of shop time to get the slide off, gun looks o.k. Just need a new barrel. I have loaded 16k rounds this year with no problems. What is the chance of a prime not Igniting all the powder? The Dillon is spot on with the powder drops. I check every 50 or so and they are with in .1 either way of 3.0. MY LESSON LEARNED......If I have a misfire....my time is already shot for the round.....STOP AND LOOK. Its hard when the name of the game is speed. My fastest time for six plate was 1.97 seconds. It dosnt give you much time to react.
