Howdy, Bought a new FN M70 7mm Rem Mag and am having feeding issues. No matter what type of ammo I am using the round does not feed smoothly into the chamber. I typically have to pull the bolt back 1 or 2 times and push again to finally get the round in the chamber. Most of the empties come out with scratch marks on the brass as well and I stuck my finger in the chamber to find small shavings of brass. Help? Ideas? Thank you.
