I am working with a 416 Ruger Alaskan that does not like to feed the final round out of the magazine. It feeds the first two DGX softpoints almost every time and jams on the third. The DGS solids feed ok. This is the second 416 Ruger that has not fed well. The first was an African model and after two trips back to Ruger that didn’t fix the problem it was returned. This second one is better but still not right. Is there something that should be polished to make it work? Extra strength magazine spring? The first round almost always feeds fine even though it’s off the same rail. Any thoughts would be helpful and welcome. I don’t want to send this second one back. I want to make it work!
