I trimmeed a few .015 short

[SporterII]

Target case length for these 223 Remington, 1.750 trim length.
I ground out a couple before realizing they were short.
1.735, 1.740, and 1.745" long.
Are they all trash?

No. they are good.

3 cases? If you're really sweating it, throw them away. If not, load 'em up and let 'em fly. They'll grow back .015" short isn't going to hurt a thing as far as case length is concerned, just don't make a habit of it

Thanks, I'll try not to let it happen again.
I suspected they would still fly, I do however value experience and want to ask.

What brand cases are we talking about? Are they for a bolt action or semi auto? Are you loading for accuracy, plinking, hunting or load development? They are completely usable but dependent on your purpose.
