I've never used bb but I have used lacquer coated stuff before in my AR. Never had any kind of build up. The only problem I had with lacquer was a problem from the factory. A unfired round was stuck in my chamber. A good smack of the fwd assts. knocked it lose. After measuring the casing I found that there was so much lacquer on it that it made the casing to big for my chamber.orangello said:It runs fine in my SKS. I have heard that the laquer coating can accumulate in super-hot chambers; i haven't noticed a build-up yet, but i don't just dump twenty rounds for fun very often.
Ew... That sucks. I always have my Calculator App up on my phone at gun shows so I can see the price per round for the "bulk deals" the ammo counters offer. Last gun show I went to, there was a counter asking about 35 cents per round for .223 brass in the 50-round packs. If you bought 1000 rounds, the price went down to 34.75 cents per round.Sometimes you have to watch buying in bulk. You can get screwed. I picked up a 500round can of Tula for about $150 from academy. About 2 days after that I went back to academy to buy a couple 20round boxes of it. $4.90 a box. That is about $125 for 500 rounds. Yea I was all kinds of p**** off.
