Or the ammo isn't powdered enough, which is what I suspect with short-stroking Russian ammo intended for the US consumer market.Tulammo is not coated, the cases are bare steel. If you are short stroking with this ammo, you either need more lube or your upper isn't gassed enough. Jim
Yep, I can't imagine where anyone got the idea they are bare steel. The poly coating has been blamed for all sorts of ills but I also agree it's not the problem. In one of my AR's the Tula stuff causes failures to extract and/or feed about every 5th or 6th shot, it's a shame too because the stuff is actually pretty accurate out of this rifle. Fortunately I didn't buy a bunch of it, but that pretty much ends it for me and Tula .223 as the rifle in question will digest any brass cased ammo with no problems whatsoever.The cases aren't bare steel, there is a poly coating. But that's not the problem, IMO.
