Ramtough14 did this ever get taken care of? I too am having that issue. I have the X bolt HC LR McMillan in 6.5 creedmoor. Gun shoots great, but if you load the magazine and shoot - 8 times out of 10 the magazine falls out the bottom. I called Browning and the man I talked to said he'd never heard of this, but offered to send me a new magazine. The new magazine didn't fix the issue. I was trying to avoid sending it back to Browning, but looks like I may have too.
