"The dead trigger is due to dropping the hammer before the gun is in battery."
From "Speed Shotgun" by Patrick Kelley published in Front Sight magazine, official journal of the United States Practical Shooting Association. Somewhat dated from 2001, but nothing has really changed.
"Using the same videographic techniques that we applied to the 1100, we found the limit for the Benelli: 13 hundredths of a second. That's it. Any faster, and the hammer follows the bolt."
"The initial reaction of many shooters to this information is, "Who cares? Who really goes that fast?" or "Where would I use that speed?" Practical shooters (and some tactical shooters) are different. This is why I penned my "on the range" experiences. If you KNEW that your pistol stopped working at .13 seconds and your ability exceeded that, you would be at the gunsmith getting it fixed. Why should you expect less from your shotgun? If you worked on a SWAT team, and the Benelli was your main shotgun, wouldn't knowing that you were carrying a gun guaranteed to fail at under .13 second splits give you pause?"
"Okay, drum roll please. Will the real world's fastest cycling shotgun please stand up? What? We have two guns standing? How can this be? We can thank the people at Winchester and Browning for this situation. They have unwittingly given us a choice between two "world's fastest cycling shotguns." The Browning Gold and the Winchester Super X2 are both built on the same basic platform, and these guns haul!"
" I got a chance to spend a little time (very little) with the Winchester Super X2 and found what may pull me away from my beloved Auto 5. After a few speed drills on three pepper poppers, I was already well pleased with this self-loader's performance. Using 00 Buck loads (does this thing smooth out recoil or what?) I ran a three-popper course with each popper a yard apart and 12 yards down range. From the port arms position I was able to "draw" and knock down all three in just under one second. Considering a reaction and first engagement time of .68, split times between the next two poppers were 12 and 13 hundredths respectively. This is as fast as my Auto 5! At this speed, the Benelli's hammer follows the bolt!
Idaho state police officer David Neth was kind enough to let me perform this test with his personal Winchester SX2 Practical. He also demonstrated this shotgun's true capability by pulling off some 11 hundredths splits along with a handful of 12's. To top that, he beat my personal record for the fastest five shots. This is a little thing I have been doing since the speed bug hit me. With the timer running you let loose of five rounds as fast as you can, counting the first shot as zero and totaling the remaining four split intervals. My best to date has been 56 hundredths. David amazed the small gathering at a 3 gun match in Winchester, Idaho by firing those five shots in 51 hundredths! The splits were three .13's and one .12. This gun is full auto fast! By the way, this was with Federal 00 buck. No, not the low recoil stuff, this was Federal MAX 2 3/4 Classic."
