I have a 450 Bushmaster AR and I really like the gun. However, the only ammo I have been able to find is Hornady American Whitetail. My gun zero’s great but it doesn’t always reload the next cartridge. I killed an 8point last season and had to manually eject casings. Not fun when the target is running? I was told I needed different ammo that Hornady whitetail’s specs aren’t precise enough. I am curious if anyone else has had this issue? If so did different ammo solve the problem? Thanks in advance!
