So I made the mistake of buying a ton of this remanufactured ammo from ammoseek without trying a few first.

Well about 3/10 of the rounds are too big or jagged around the neck and I have had to pull my barrel or buffer 3 times to unjam lodged rounds.

Is there a way to repair these that would be cheaper than throwing them out and replacing (about $300 invested)? I know nothing about reloading but I would think there is some kind of reamer or tool that might fix this by hand.

The diameter seems to big where it is shiny in the pic and at least one was stuck on the edge of the shell where the bullet goes in.

Give a few a kiss with a Lee factory crimp die, might work.

If the rounds are not to saami spec then send them back to ammoseek or whoever you bought them from. Even remanufactured ammo has standards they need to hold.

FWIW I stopped buying factory reloads a long time ago, learned the same lessons and in one order lucky I didnt blow up my gun. Factories just cannot control the fatigue of used brass.
 
Can it be saved? Probably. Is it worth the effort? Probably not. You should contact whoever sold that to you and give them a chance to make it right before investing time and energy into it. After all, that's why you bought ready to shoot ammo instead of loading it yourself, right? No extra effort.

You will NOT like hearing this but if it was me? I would NOT put another one in any gun I owned. If whoever did it was that sloppy I would NOT trust them. Best bet would be pull it apart for scrap. If one blows in a gun? Write it off to a learning experience
 
Since you are not a reloader, your options are limited. Even if you were, as stated above, it would be a lot labor to rework them now.

Your best bet is to attempt to recover your money from the seller due to product defect. Hopefully, not too much time has elapsed and you paid by credit card.
 
It appears to be .300 BO ammo and I'm guessing brass reformed from .223. I'll also guess that the brass is some that is too thick in the body to make appropriate sized necks on .300 BO. If that's the case there is no fix short of pulling them down, reaming or outside turning the necks and then reassembling them.
Look here for a list of good and bad headstamps;

If you reload, I would try running a few into a Lee Factory Crimp die. It almost looks like a similar type crimp on there. But not as complete of a crimp.

Here are examples of how much crimp can be applied with Lee FCD.

It looks like they crimped them to far below the case mouth. That could be because the case was not the proper length, too long?

Do they all look like the example in your photo?

Do you have calipers that you could use to measure overall case length?
 
If you can't return them I would toss them or give them to a reloader. The equipment you would have to buy to fix them will eat up the $300 very quick.

If you do decide to pursue fixing them I would start with a cartridge check gauge:

It will help you identify what part of the round is out of spec. But you are headed down a rabbit hole and there is no telling where it will go. It looks like a Lee collet crimp die and a reloading press would fix the problem but you really need to identify the problem first, hence the cartridge check gauge.

This is exactly what I was thinking. If so, another option might be to get a dial caliper and measure the outside neck diameter of each round; it would be a quick and easy way to sort out the fat ones. A cheap Harbor Freight caliper should work fine.

If they were loaded by a reputable (licensed) re-manufacturer, they should make it right. If they're someone's unlicensed garage reloads, they're iffy at best anyhow.

The other possibility is that your rifle's chamber is on the tight side, and the whole batch might shoot just fine in one with a looser chamber. It's a good excuse to buy another gun, right? :)

A long time ago I loaded a batch of .223 ammo and didn't have my sizing die adjusted quite right. They chambered really hard in the rifle I was loading them for, so I shot them all up in the old Mini-14.
