Chambering a Round
 
I've heard from many sources that you can only chamber a round so many times before I becomes unsafe to fire. This is one of the reasons you should cycle your defense loads. Now, the odd thing is that I've they never say how many time you can chamber a round before it would be considered unsafe to fire.

Does anyone know this? I don't unload my EDC except when going to the range to train/practice or if I'm cleaning the gun. So, how many time can I chamber a round before I should cycle it out?

I have heard that chambering 45acp shouldn't happen more than a couple of times due to the bullet getting set back into the brass and compressing the powder charge or something.

Varies with different ammo and different guns. KNOW your equipment.

Yes, it does happen.

Wow! That's some eye opening crap! :eek:

My EDC is 9mm. It looks like I'll be investing in a micro meter.

Does this only apply to center fire handgun rounds? What about finger oils leaking into primer of a shotgun shell?

I am carring a mix of brands these days, but I have always liked the Sellier and Bellot 230gr .45 ACP for their sealed primers and bullet.
I should run a few tests with these. I would like to know if the bullet set back breaks the seal or if the seal helps hold the bullet.

hmmmmm .. .. .. something to try.

Since I carry regularly and shoot often on my property, I end up with a mix of brand in some of my mags. I may not even know which round has been chambered one, twice, never or forever. I do try to keep one mag of PD ammo, but indeed, I chamber, unload and rechamber the first two rounds fairly often.
