    got some bullet setback , would you still shoot?

    I noticed My carry ammo in my Ruger LCP looked rather short and didn't want to chance shooting it or carrying it any longer. The following are the Overall length "OAL" of the cartritges

    Brand new never cycled in the pistol is .968" when I measured some extra ammo I had still new in the box.

    Used, as in cycled through many unknown times during unloading and reloading of pistol for cleaning, or dryfire.
    .924
    .931
    .946
    .950
    .954
    .957
    .964
    .966
    .968

    Are these still serviceable you think?

    I cycled a batch of reloads and commercial .45 rounds ten times each and they setback from .010 to .002, and not the ones you might think were the worst. I don't put much thought into setback. I'd fire them at the range, buy some fresh one, and stop recycling ammo so much.

    Fmj or hp? +P or not? I would not run the shortest 3 thru an LCP. a more substantial barrel should be ok.

    Max setback of 0.044" is not a lot. Shoot it and don't give it a second thought.

    Setback of 0.10" in .380 would cause me concern.

    My Lyman manual shows 90 gr loads of 0.900" OAL, and I think that's a reasonable lower limit for OAL.

    I would not fire the bottom 4 or 5. It does not take much setback to increase pressure. The correct way to cycle rounds is once it is chambered and unchambered it gets put down one in the mag then you are never continually cycling the same round. Once they have all been chambered you replace them and shoot them up. Are you one of those guys that loads and unloads all the time? My carry guns get chambered and left that way.

    Your Lyman manual also lists a much more conservative load than a factory load with canister powder.

    I measure and mark my in-gun carry ammo and put the longest in at the top. After a few times in and out of the chamber it gets cycled down into the magazine. Another option is to fire the chambered round when out on the range and replace it after range time.

    Risky, of course, but, out of irresistible curiosity, I once fired several Federal 9BPLE +P+ rounds that were fully setback in my S&W 915 without inducing a dreadful chamber detonation.

    I'm not current on what powders the various factory loads use, but the 380 is like the 45 and 38 Special. There are older guns in these calibers still in service that cannot tolerate high pressures, so I expect everything from a factory is loaded fairly conservatively.

    IIRC the real issue is when you compress the powder charge. At that point, you really need to watch for pressure signs. Not really an easy thing to do with an autoloader. You've gotten some good advice already. I would shoot the ones with a small amount of setback, and if I didn't feel good about the shorter ones, I'd just throw them away at the range. Ammunition is fairly cheap.

    And stop chambering and re-chambering so much. I only rechamber when I clean my carry gun.

    Smith 915 is not an LCP.

    I'm aware of that. But, regardless of the firearm involved, I'm no longer that concerned with bullet setback.

    Yeah I know the only reason I rechamber is when Im cleaning and have removed that round from the chamber to do the cleaning or the same for when I want to dryfire, that round needs to be out of the chamber.
