Mike,
What's wrong with Wolf in AR-15 aside from accuracy (just use it for plinking)? Are you talking about any possible damage or excessive wear?
No, it's mostly just the increased dirt output and weaker energy of
wolf .223 compared to M193 ball. (Wolf will not work well in some
fussy rifles, on the other hand some guys use it as a "test"... if the rifle will
feed wolf, then itll feed anything.) I havent heard of anyone blowing
up or damaging a rifle with it yet. It's just my preference when borrowing
other peoples guns to not feed wolf in it, unless it's an AK. In my
AK, I use wolf all the time... but the AK is a rifle that you can get away
with cleaning once a year, if that.
Apparently wolf .223 is popular with MG shooters as well... and if you figure
anyone would have a problem itd be them, due to the rediculous amounts of
heat involved as well as the greater chance to not notice a malfunction during FA fire.
