I recently purchased a model 7 300 wsm. The thing shoots really good with nosler 180 accubonds however I am having some issues with feeding. If I just put one shell in the mag it feeds find. If I put two in the mag and one in the chamber I find that when I extract the chambered round the next round will either pop up through the feed rails or if it stays it doesn't feed right and will jam. Then the last round will feed fine again. Does anyone have any ideas to remedy this or am I ending up with a two round rifle ? Thanks for the help
