A friend at the range has the new GSR, and he's having feeding problems. With factory rounds, he gets frequent failure to feed problems. With my reloads (200g LSWC, crimped to .468") he has no problems. He's tried several different brands of ammo, same thing. His barrel could have an extra tight chamber, but I hesitate to suggest having it opened up a little my our local gunsmith, it would void any warrentee I think. Until he gets it figured out, I've been giving him some of my reloads - but I keep thinking of the liability issue of that.
