I will adjust my lube process to prevent this on future loading.
Forgive me if this sounds harsh, but you don't need to adjust you lube process as much as you need to adjust your
THOUGHT PROCESS!!!!
You are NOT PAYING ENOUGH ATTENTION to what you are doing!!!
Seriously, take a step back and consider what you did. Not the dents, all of us have overlubed and dented a case or three over the years.
YOU went on and LOADED THEM!!!!
This says you did not notice the dents until AFTER they were loaded ammo. Which means you are simply not paying enough attention to what you are doing!!!!
And don't blame it on a progressive, either.
ALSO, loading ammo before you have the gun to shoot it from is (forgive the ancient homily) "putting the cart before the horse".
It doesn't matter if everything is new and "loaded to spec", without the gun to test it in, it MIGHT NOT WORK! Sure, it should work, but because each individual gun can have its own quirks, ammo you make without the gun in your hands to check, can only be a "maybe" it works thing.
You don't HAVE to learn how to crawl before you learn how to walk, but you really should learn how to walk before you enter a marathon race!
I'm trying to save you at best some frustration, and at worst actual injury and/or damage to your gun!
My point is, because you let this minor goof get all the way to loaded ammo, your QC (at all points) is suspect.
The thing to do is when something isn't exactly right, STOP. Figure out the problem (which is always two problems, at least, the one that actually happened to the ammo, and the problem of you doing or not doing something that allowed it to happen), fix the problems, THEN continue.
As far as physically firing those rounds? As long as you are CERTAIN the powder charge is not dangerous, and they CHAMBER, ok. The dents will "iron out".
I would not, however recommend trying to chamber them in an AR pattern rifle. I have fired, or tried to fire slightly mangled ammo in ARs and it is simply an exercise in frustration because of the AR system.
With the forward assist on an AR, if it just doesn't quite shut, you can use the forward assist and everything will be fine, right?
MAYBE.
Or maybe you just jam the round in tightly enough that you cannot open the action by hand, but not closed enough you can fire it. I've had it happen. You wind up taking the rifle apart and using a drift on the bolt carrier to get it unlocked.
Ran the same bad ammo through a mini 14. A good smack on the op rod would generally shut the action and the rounds fired. The couple of times it would not, a good smack on the op rod to open the action always did. With a Mini 14 you have leverage an AR does not.
Step back, take a deep breath, SLOW DOWN, and think about what you are doing, what you should be checking, for EVERY step of the process.
I know what is driving you, been there done that, and made almost all the stupid mistakes, including a 110,000psi "grenade" 6 inches from my face!!!
Trust me, you do not want to do that. ALWAYS wear eye protection!!!!
Brother, I would save you that pain, if I could.
Good Luck!
