Well actually I think what most people fail to realize with with wolf ammo is that it is steal cased and has a lack of quality control. It is cheap for a reason, steal is cheaper than brass and rusts so it must be coated in a compound to prevent moisture from reaching it hence Laquer or polymer. Either melts and becomes sticky when exposed to extreme heat or pressure which are both present when firing a firearm. Wolfs main and original market was for Kalishnikov's and Sks's and similiar weapons that have been designed for use with steal cased ammo, these weapons have much lower tolerences than a finely crafted ar15/m16. With this they will handle junk ammo and love it. You're expensive top shelf colt/bushy is going to gag and choke on loads of melted laquer and polymer in its precision chamber and fine fiting compenents. I've owned 4 ar's and never shot junk ammo, never had a single problem other than a few slight jams when I was learning how to clean and maintain one, since I've fired 1000's of rounds, all brass and high quality... Really you should also consider your firearm is a valuable investment that you spent your hard earned money on, so why abuse it with junk. Steel ammo above all else erodes the head space in your barrel and is harder on all working components than brass... so above all else its burning out your gun just a little bit faster each time aswell, hope that helps shooters ~
