I found some info by bflee about bending the magazine guide forward.
It has helped somewhat, I will say it takes quite a bit of force to bend that guide, so emphasis on the large needle nose pliers to give you the leverage you need. Bending the guide completely eliminated the lateral play of the mag in the mag well. But now my bolt hits the forward guide lips on the mag, of course they can be filed down. As far as the bolt grabbing the case rim, it does but barely. I’d guess by only .010-.015”. The mag still has play up and down but not nearly as much as it used to.
