TonyAngel, thanks for the apology and give it no further thought.
"I've had quite a few friends and acquaintences that had the problem with sticking cases. In all of the cases that I was able to remedy, the fix was to retard the timing a bit. It was as simple as that. Just slowing the cycle down just a bit to allow the steel case a bit more time to contract before the extraction process began. None of their problems were associated with anything sort of gum being left in the chamber by the ammunition."
But isn't the counter arguement that the problem with steel that it fails to expand enough to fill the chamber as indicated by what some consider to be just carbon in the chamber? Just out of curiousity, what method did you employ to slow the timing?
"If you look at this from the flip side and assume that your argument is true, then it could be said that everyone shooting steel cased ammo would have a build up of gum in their chamber and they should be having failures, but they aren't."
Not necessarily. Quantity of ammo fired, speed of ammo fired, type of chamber (.223, 5.56 or wylde), metal of chamber, amount of lacquer on ammo, cleaning methods, are all just a few of the potential variables. Even extractor condition is going to be a variable. I just think the arguement that lacquer can cause issues makes sense. Its sort of like when the original M16s came out. The conditions under which they were being used made them prone to malfunction but obviously they did not all malfunction.

"No, but you are accepting YOUR point as true, even though IT DOESN'T have sufficient evidence."
What point am i accepting to be true without sufficient evidence? Saying an explanation sounds plausible is not saying it is true.
"And no, the lacquer to seal around the primers and neck as a sealant, is NOT the same as the case being treated with lacquer or polymer to prevent it from corroding or the steel from rusting. chipped lacquer sealant does not mean the case lacquer/polymer chips or melts. The chemistry of the elements are different."
I realize that lacquer was used all over to prevent rust but was also under the impression it was used a sealant as well. If the sealant is another material what is it? If the only lacquer is a thin coat on the case then it may be very difficult to see even if one is able to make it run with heat.
"FWIW: There is brass case ammo that has a lacquer sealant around the primer and sometimes at the bullet/case neck."
Yes, i believe it, whatever it is, is used on the primer of Yugo brass cased 7.62 x 39 ammo.
