I just got bought it new 3 days ago. I havent shot it yet, but I was given a box of Monarch 100 gr full brass with soft tip. When I put one in it wouldnt breach closed. So I tried a Winchester ballistic tip and it worked fine. Can anyone tell me if they or anyone they know have had problems with the Monarch bullets. I will be using Remington Core-Lokt bullets to hunt with but havent bought any in case the gun has something wrong with it.
