The shell casing's little button thing (primer?) is already been used....forgive me for my terrible bullet terms.
 
Bad batch of primers, I think. I've been shooting the Remington Core-Lokt for years without incident. However, in sighting in a scope the other day, 2 of the first 10 out of this particular box would not fire. Firing pin operates properly and bolt face is clean. The ammo in question was stored in a dry, in-house environment. Other ammo (even other Core-Lokt ammo from a different box) fires just fine. Regarding the ammo in the pics, I attempted to fire one of them 3x and the other one 2x. Nada.

I didn't have time to sight in a new cartridge, and the experience didn't leave me with the most confidence in stand, even though I was using ammo from a separate box. I'm going to try that new LeverEvolution .30-30 ammo from Hornaday. More expensive, but supposedly more accurate out to greater distances.
 
Contact Remington. See if you can get anything out of them. They've been known for bad rimfire priming in the past. Bad centerfire priming however, is much harder to botch.
 
I sent them an email on Friday. However, I called today, and they want to see the cartridges along with the box.
 
Look at the cartridges you didn't try to shoot. Is the primer seated flush? If it's protruding even a tiny bit it isn't seated, and when you try to shoot the firing pin has to push it the rest of the way in first, and that takes up enough energy so it doesn't get crushed properly. The primer goes off but so weakly it doesn't ignite the powder. If you look close and hold a straightedge to it and shine a light on the other side of the straightedge you'll see it isn't flush -- it can be hard to see. It doesn't take much.

I have seen that in hand-loaded ammunition and the factories can make every mistake a hand-loader can make.

It's also possible the primers are bad or the powder is bad, but I think it's more likely that the primers aren't seated. The advantage of knowing that is you can sort out which are the bad cartridges once you know what to look for, and when you send them back the manufacturer can see they're bad without having to test-fire any. (They'll probably look for that without being told.)

A different gun that strikes the primer harder might fire the bad cartridges, but that gun probably isn't as accurate -- heavy trigger and heavy strike to throw you off your aim. I wouldn't blame your gun, unless you just got a trigger job done -- he may have overdone it.

Good info. Thanks. I'll straight edge them before I send them back to Remington.
 
My bet, the primers are duds.

But not being seated properly is another possibility. You could inspect the rest of the box to see if any of the other primers are not flush with the casing.
 
Hey Guyon , Let us know how this goes. I have been using 30-30 170gr. core lokt for 20
years and have never had that happen.

Well, to begin with, it's 328KBytes. Could you not have resized it? Or do you insist on consuming bandwidth and slowing things down for those still stuck with dialup?

Aside from that, the presumed subject, the dimpled chads, is neither centered nor in focus.

At least the color balance looks good.
 
Light primer strike, hard primer, dud primer, bad powder, improperly seated primer, contaminated/wet primer.

I loathe Remington ammunition, EVERY single ammo related problem I have ever personally encountered were from them. The only thing I now avoid more are the mystery reloads selling in the zip lock bags at the gun show.
 
Psycho Boy, The NRA did an extensive test of various gun oils and cleaners and found many caused definite ignition problems especially with those with penetrants....Various primer problems can occur .I've seen primers that had enough power [brissance] to push a 44 mag bullet out of the case and into the forcing cone which jammed the revolver. This without igniting the powder.!! I've had a batch give excessive pressure in about 10 % of the rounds .If you find such a batch just dump it .
 
Another remote possibility is the flash hole... ain't a hole! :confused::D
Most often occurs in reloading as the original hole gets clogged and fussed shut.. However, almost impossible to tell if that's the case from a factory load unless you disassemble the round. Morelikely, though, is as been said: either a dud primer or not seated deep enough...
 
I did look at the primers. They are seated flush on the rounds in question, but this fact may be a function of having been hit twice and three times, respectively. Of the unshot cartridges, I do see a couple that have primers very slightly above the surface of the rim. I'm sending everything back to Remington so they should see these rounds as well.
