Creep, reset, and overtravel

If we define creep as the distance between when sear movement begins and hammer fall occurs, overtravel as the distance between the triggers breaking point and stopping point , and reset as the distance the trigger must move forward for the disconnector to release, we get the following:

All measurements are of the movement of the tip of the trigger where the trigger is closest to the bottom of the trigger guard. Although the trigger tip moves in an arc, measurements are linear from point to point.

Colt- 3/32 inch creep, 2/32 overtravel, 5/32 reset
Sport- 2/32 creep, 3/32 overtravel, 5/32 reset

I don't know about using only the POS Colt mags with the Colt while the SW gets the good PMags.

You should use both mags in both carbines.

I am surprised at some of those numbers....especially the Black Hills...I thought that would do better.

Not bad though, considering he is shooting with Magpul BUS rear sight. I'm not a fan of those.

No, He is right to use the same items that come in the box for head to head. If the Colt mags are POS, which I don't know so have no opinion, then the S&W should not be gigged for magazine issues that S&W had nothing to do with.

If the Colt mags are an issue, it would beg the question: why are they being shipped with Colt carbines? In any event, if a stoppage looks to be mag related, that mag will be tried on a Bushmaster. If stoppages occur with a suspect mag and the Bushmaster, the mag will be pulled as damaged and the mag data recorded as such. When a carbine goes below 7 working mags, more mags will be purchased because our poi calls for 7 magazines.

The accuracy testing is being done with a Leupold VXIII 3.5-10x 50 in a Burris mount. We plan to slap the Leupold on the Carbines several times to measure accuracy at several points along the throat erosion process.

Sorry Matthew, there have been so many posts in this thread, I forgot about that....

Now I am really surprised on those numbers! Are the rifles locked down in a sled, or is this shooting from a bench with sandbags?

The triggers feel different, more so that the small weight of pull and creep figures reflect. Since we are here to report data, not make subjective conclusions, we have been trying to find a way to measure what we are feeling during the trigger squeeze. It may be a moot point, because the triggers seem to feel more similar as they get broken in. We plan to take fresh measurements after 1200 rounds.

i had a feeling there was more to it than the numbers. we may find that to be the case many times in the shootout.

many times subjective feel is valuable if the sample size is large enough.

i commend your testing procedure and thank you for your efforts.

may the best rifle win!

would it matter that much if both where tested in the same manner and was repeatable?
