cartridge OK to use?

[DonVoigt]

The bottom groove is not a "cannalure", it is simply the extractor cut or rim "rebate".
A cannelure is on the projectile and is where the case neck crimps into the bullet.

I agree though, toss the ammo, it is not worth the risk! In fact it would have negative value to me.
If you can figure out what the semi-rimmed lead rounds are, they may be "collectible" to someone- but not for shooting.

JMHO.
