Just bought 1K of Silver Bear 62 gr BTHP for a great price. I have shot it it my Target Mini 14 3 round strings only and have had no problems but I got more of the ammo for my newly aquired GB model. It was manufactured in 1995 but I still have not got a reply from fuger on barrel twist. nyone out there use this ammo in a mini? If so any rpoblems, I know my H&R Ultra will shoot two rounds and the third will stick in chamber and has to be forced out, I guess to steel case expanding.
