I am having a problem with my 300WSM feeding reloads. A round loaded from the magazine will not seat past the extractor. The bolt does not go into battery, remaining slightly open, basically the distance of the round sitting on the outside of and on top of the extractor. If I drop the same round in the chamber, the bolt will close - the extractor will move around the cartridge. I have mic'd the base of the reloaded vs new rounds and there is only .001 difference between the two. The reloads are completely resized. The reloaded cartridges fits just fine in the chamber when manually placed there (no tight spot- drops right in). Factory ammunition exhibits no issues. Any input?
