Are these ruined?

Well, they likely won't shoot quite as well as virgin bullets, but depending on what you are doing, that may not matter. I usually use pulled bullets for practice.

look fine to me,

Honestly, what do you think they look like after they leave your barrel in flight?

I'd shoot them. Great for plinking.
I've bought pulled 22 caliber bullets for plinking loads.

take some Flitz and polish them! good as new

Maybe they aren't 100%, but they're still worth shooting

Anyone would appreciate those bullets if gifted to them. Not to worry, they will shoot and are worth the postage to send them.

They look good. They will group great. I've pulled lots of bullets, once I had to pull 200 because I loaded them up with the wrong powder. After pulling them I just reloaded them and had no ill effects.

If you are giving them away the new owner will be able to shoot them quite well so go ahead and get the other 90 done.

You didn't hurt the bullet back where the rifling contacts the bullet. I wouldn't worry to much about them.
Send them.

I shoot a lot of pulled bullets never noticed a difference but I'm not exactly a precision shooter.

Agree that a serious competition target shooter with a rifle that cost more than my car could probably notice a diminution in accuracy. For most ordinary hunting, plinking, casual target shooting, I doubt it would matter a bit.

I'd use them to warm up the barrel before a session. I usually use some old bulk ammo to fire a few shots before I zero. I'm always zeroing or confirming my zero when I shoot and I don't want to waste any of my good rounds on nothing so if I had them I would save them for the first few shots where I don't make any adjustments.

I pulled .224" 5.56 fmjs with channel locks. No harm to accuracy @ 100 yds. The base/shank needs no damage..

Good for practicing offhand at 100, they will shoot better than I do enough that it won’t change the score much. Further out or more supported positions you will likely see a difference.

Run them through a tumbler and shoot them.
Don't use them for trophies or cash award matches.

Measure them. If still in tolerence, and round, use them like new bullets, The crimped portion probably won't have any effect on accuracy...

I'd happily load those up and shoot some coyotes at +/- 100yrds with them.

As is, all I've got are a bunch of 55gr FMJ's

Shoot'm or share'm, whichever tickles your toenails. I would.

I could be wrong but that looks more like a crimp ring than a collet ring. I've never seen a collet ring that deep. As others have said, I wouldn't use them for competition but for plinking they will be fine.

A noted gun writer did a test a number of years back in an effort to quantify the difference in accuracy of pulled vs new.
He concluded that there was none as the pulled bullets generally out shot the new!
Actually, he discovered that several flawed bullets were culled after being pulled that probably skewed the results! In favor of the pulled bullets.

Choot em!

After those bullets hit the throat and enter the rifling, the pull mark will be irrelevant.
