Depends upon the gun. But for most centerfire guns, the answers are yes and no.
They work very well for testing if your "flinching" when firing. Need a buddy to sneak one or 2 in a magazine without you knowing if and where.
They work, but fired brass works about as well, and is much cheaper!
ha ha ... that really clears things up for him.
I got some when I built my 1911 and found them to be helpful when testing feed, cycling, safeties, etc.
If using spent cases instead of snap caps, should you resize the cases first so that they're in spec? For example, if one was checking the cycling in a Garand.
I got mine from s.t. action pro. Not the cheapest, but they've held up nicely to lots of use/abuse. I think I got the recommendation from someone on NES.
what does "snap caps protect the barrel from being peened by the bolt."
On open bolt guns, there is no firing pin mechanism per se. Just a pin welded/formed on the front of the bolt that as the bolt comes forward, the pin impacts the primer and there she goes. So closed bolt, there is a mechanical pin which moves inside a bolt, which also moves to allow for ejection. Open bolt, the pin is fixed and the bolt moving for ejection/feeding reasons doubles as a firing mechanism.
what does ... "tap/rack drills" mean? thanks
When shooting any mag fed semi/auto, what do you do when it doesn't go "bang"?
"tap/rack/bang" (and it derivatives, ie some say slap/rack/bang, tap/rack/shoot, tap/rack/pull, tap/rack/assess) is the immediate action drill instilled in most shooters.
Meaning when the gun doesn't shoot, some statistic says most failures are caused by a poorly seat magazine, so step 1. Tap (or in real life typicaly slap the mag) up into the mag well to ensure it is in there "good", step 2. rack the slide/charging handle hopefully chabering a new round (and possibly ejecting a bad round) step 3. "bang" ie. hopefully this time when youpull the trigger the gun works.
As for dummy's (snap caps) you can do this drill safely at home "dry" with a mag full of dummy's, or better yet, when at the range when loading up you mags "hide" a dummy in a few. somewhere during your shooting you will press the trigger and only get a "click"forcing you to do a "tap/rack" drill.
I have never been able to hit anything with them....
