As I posted a couple of months ago, My Steyr doesn't at all like WWB. I wasn't sure if it was all Win ammo or just those. I am happy to report that I put 450 rounds of Ranger 124gr +p through it today with 0 issues. I know that is a lot of expensive ammo, but this is what I plan on carrying out of state, and when I get my armed bodyguard license. I still have 550 rounds left from the 2-500 round cases I got. By the way, I still don't have any 14 round mags for it and did this all with 3-10 rounders(sore thumb!!!) Where is the cheapest place to get 3 -14 round mags from?
