I would.

No reason not to chamber an AR15 indoors.  Same goes for the issue M16's and M4's I use regularly.

First key to responsible firearm ownership is understanding how the weapon works.

Seems like there is a massive lack of that in this entire topic.  Thanks all for the laughs.

yea ok
First of all when i posted, i thought the OP was just chambering live rounds in his home for shits and giggles. It didn't occur to me at that moment he was getting his HD weapon "hot".

Side note; That isn't ceramic tile. It's porcelian tile which is stronger and heavier than ceramic.. Ceramic tile would have spiderweb cracked. That is porcelian tile on cement board applied with thin set.

Hopefully the chamber at home vs. don't chamber at home debate hasn't scared off the OP.

He still hasn't provided any specifics about the ammo or gun beyond the fact that it's TAP of some variety. You'd think a guy who made this his first post would be all over this thread with details as legit questions are asked.

he posted pictures of the boxes showing the info and lot numbers.

No i was not scared off, just got busy enjoying the nice weather on my Yamaha R6. Had to test out the new Wiz Sparky knee pucks i finally got my grubby paws on.

And sorry for not responding with the specifics right away, i thought the thread was beginning to run in circles. Like this gentleman pointed out i indeed posted a picture with all the ammo specifics. The rifle used was a Smith & Wesson M&P and the only modification to the actual inner workings of the rifle is a Timney Trigger which does not contribute to slam fires. I also do not own a micrometer to measure the exact primer strike depth.

Nothing wrong with enjoying the sun and open road!

The trigger could definitely be contributing to the failures to fire though. A light hammer spring combined with what are probably hard "mil-spec" primers is not a good combo. I agree the slam fires are a separate issue and argue against there being hard "mil-spec" primers so who knows. The problem is that you have two issues that contradict each other. I guess if Hornady did a lousy job seating primers that could be the problem. High primers could absorb some of the firing pin energy resulting in light strikes while also causing the occasional slam fire if the primer is way too high.

The only way you're going to figure out what happened is to have the rifle thoroughly inspected by a competent gunsmith to ensure there is no issue with the gun itself.

Not trying to pick a fight or anything but did the M&P come with that rail and stock? If they were installed by someone could the barrel be mis-installed and somehow contributing.

To answer your question Lomshek, no they were installed by me, and im not sure how a buttstock could affect anything in the discussion. The rail on the otherhand could play a small part in barrel allignment but again i dont see how that could be a contributer, more or less just a quick adjustment of the knobs on the acog and we are back in business.

Maybe im missing something here, if so please correct me.
