I picked up a 6.5 SAUM for my son that sits on a 1500. Took it out today and shot decent but feeds awful. Basically if 2-3 rounds are loaded into the mag minute bolt clears top 1 or even 2 rounds pop out the rifle. I was able to load two and if cycled quick enough will work. 3 rounds with bolt closed on an empty chamber is really tight. even if I load three 1 in chamber and two in magazine and fire the one round as I cycle the bolt the second round pops right out the magazine. A smith recommended the ptg box and aics magazine. Wondering if or which magazine will even work with these fat 6.5 saum cartridges or should I just try a new follower and spring? Thanks I am kind of panicked as this is my sons bday gun for 6/17 trying to get it dialed for him. thnx
