cbc M80 Ball Ammo- Is it any good?

Picked up some of this for $25.99 for 50 yesterday. Is this a good deal or is it junk? (7.62x51 Nato 147 grain FMJ)

Thinking of getting more if it is good for pinking.

Shot some and found it to be better than other surplus I've shot in the past. Picked up 5 more boxes...
