Hello,I am having feed issues with bulk pack ammo fed,win,and rem they strip from the mag and the nose hits the bottom of the breech face at the top of the feed ramp.I only had a handfull of round nose and they fed ok, still had one jam half-way in. do these only feed solid round nose? should I call tac-sol? up to this point this thing took anything I fed it but would like to set it up for steel challenge. thanks
