    45 ACP Knockdown Power

    I picked up a Sig P-220 DAK police trade in. So far I'm liking it. After racking the slide it goes into a half cock condition. This makes the trigger pull very smooth and light.

    That 45 slug, boy can it hit. I ordered an Arsenal Mold, brass, two cavity 230 gr Keith bullet. I've powder coated these. I've been working up a load for it. This afternoon, I had 50 rounds to put through the chronograph using Accurate No 5 (various charges). At round 14, I had an opportunity to experience the knockdown power of the 45 ACP. Talk about a One Shot Stop. That 230 gr 45 slug hit the chronograph, knocking it down from the table I had it sitting on, then threw it about 15 feet before it ran into the target stand. DRT.

    The 45 load development has run into a snag. I also had about 70 rounds of 44 Special to run through after I finished with the 45, that now, also, needs to be put on hold.

    I also learned that I have more work to do on my double action trigger pull. If it was more of a straight back pull, the bullet wouldn't have been yanked down and the chronograph would have escaped unscathed.

    I have 2 strips of 12" x 4.5" x .375" rolled steel which sit in front of my chronograph at a 30-degree angle from vertical, for exactly that reason. So far, I've been lucky, but I've seen two "Boone & Corckett Trophy-grade" chronographs that have bitten the dust when they "undertook a threatening posture toward the shooter" and left them no choice but to dispatch them.
    Most chronos are now built with the expectation that, at some point, they'll intercept an errant missile. You might enquire of the manufacturer about a refurb.

    I went to the hardware store and bought some 1/8 wood dowel rod, they are cheap and cause less collateral damage.

    A full power #4 Enfield kinda makes a mess too !

    I know this will not stop the pain but many before and there will be others after. Take some great pictures, know that you are now in the club and figure out what your motivation is on new purchase. Spring the big $ for the Labradar or stay old school, it's just gun money!

    Back when I used those type chronos I had some 1" thick Lexan that I put in front of the instruments. Saved one of them, but, another was not so lucky.

    One of the reasons I now have a Labradar

    The old Pro digital chrono is kinda neat, you can connect it to an IR printer and print out your entire shooting session on the spot.
    These men and their hypnotized followers call this a new order. It is not new. It is not order.

    I have killed PACT screens over the years and with other draw backs of the PACT system I now have a Labradar, best move I have made, no problems with light conditions.

    This is what I used. Can't wait to set up the Labradar, no more attacking chronos to defend myself from.

    Looks like a one shot stop with placement right in the vitals.

    Yup. Lab radar has eliminated my chronograph concerns

    I used to think that the closer the projectile was to the sensors, the more apt it was to be detected. What I learned was that the opposite is true. With most chrono's there's a zone from about half to three fourths of the way up from the sensors where the bullet is best detected.

    There are two kinds of shooters. Those who have shot their chronograph and those who are going to shoot their chronograph. I belong to the first group.

    Been there done that. The upside. Got a new one with all the bells and whistles.
    “You should tell someone what you know. There should be a history, so that men can learn from it.

    He smiled. “Men do not learn from history. Each generation believes itself brighter than the last, each believes it can survive the mistakes of the older ones. Each discovers each old thing and they throw up their hands and say ‘See! Look what I have found! Look upon what I know!’ And each believes it is something new.

    See, I told you there was a club! And Kudos to those of you openly admitting the incidents. Bamboo sticks and rubber bands for me, we will see what happens after I take my box out.
