I got some bulk hornady black 62gr fmj for cheap shooting practice for the kids....shot a bit of it and it seemed to go alright, a mate tried some in his norinco and had light strikes and failed to fire a number of rounds.
I didn't think to much of it it was working fine in my howa mini.
I pulled a few and poked a 65gr game king on top at the same BTOL as my handload and tested, they shot not as good as the handload but still plenty good enough for hunting so I pulled and loaded a hundred with the game king.
Since then I have had a few light strikes and fail to fire of the untouched fmj ammo and this evening a fail to fire and projectile stuck in the lands from the gameking load.
Stupidly after waiting 10 seconds I ejected the case poured the powder out and threw it on the ground in disgust....I should have kept it to measure.
It took quite a knock with the cleaning rod to get back out.
I think what happened here is the game king I loaded was 10 thou off the lands....if that factory case had more than 10 thou head space it would both cause a light strike and jam the projectile in the lands.
I have a factory failed to fire somewhere here I think....I need to find it and compare headspace measurements with fired cases.
