KY Imports has this stuff

IMI Israeli 55 Grain, Brass case non-corrosive bright/shiny, reloadable. $130/1000

Anyone used any?

Coworker bought some a few months back.  We shot some a couple months ago and most of it went bang.  Some didn't.  One split lengthwise up the middle.  It was a WCC case but the lot he got was a mixture of WCC and TZZ with the vast majority being TZZ.  I think he might have had a few LC.  If you buy it, just look at each round and make sure it is not too damaged to shoot.  We culled several rounds from his lot due to bent bullets or large dents in the case.  Found a couple of M855 rounds mixed in as well.

So is this stuff they've swept up off the floor?

So better to go for the other IMI boxed stuff at $169/1000

I have never had a problem with Isreali ammo

Just called KY to order some Q3131 and they are all out of IMI ammo except for their funky plastic anti-terrorist stuff....
