How many times do you or would you consider re-chambering the top round in an AR magazine? When we're moving between calling stands by vehicle of course we unload so often 5 or 6 load/unload cycles per day.
As some may already know, the firing pin on an AR "taps" the primer each time a round is chambered. For this reason, I seldom load a round into the chamber and drop the bolt(that makes a bigger dimple than loading from the magazine).
In the past(when I was shooting more than now), I'd just drop that "X-times chambered" round in a cartridge box labelled "sighters" and top off the magazine. The alternative is just shoot that top round at the 300 meter plate as I've been doing lately.
Anyhoo, just let those opinions fly.
