Brass Jackets
I bought a couple of boxes of Winchester 9mm at Walmart that I hadn't seen before -- a 100 round "brick" of 115 gr. FMJ for $11.00. They still carried the 50 round boxes of 115 gr FMJ for $6.00. The brick ammo shoots great and appears to be same, except that its BRASS jacketed instead of copper. Guys, what do you think? Is brass harder on a bore? Thanks.
