I just bought a new R700 SPS Tactical in .223. The problem I've been having is that when I go to close the bolt if the round in the magwell is on the left (I.E. Rounds 2 and 4) the bolt will pass right over it unless it stick my finger in there and wiggle it. Ran about 40 rounds through it and not one round from the left side has loaded on it's own. I'm also getting scratches down the length of the brass too. I've never had a problem like this on my other 700 though it's a center feed mag so I'm sure that's why. Any ideas?
