I am trying to reload for my Winchester Model 1910 .401 Winchester Self Loading rifle. I have original factory brass (from various makers). I have two bullets to reload. Some 240 grain mold #410426 which according to John Henwood are made for the .401. I assume this bullet is .410 in diameter. I also have some Barnes 250 grain .406 diameter bullets. I am reloading with an old Mequon (Lee) Loader using IMR 4227 and the Lee Loaders recommended amount of powder.
My problem is this. While my gun digests old factory ammo without a hitch, the bolt will not close completely on my reloads. The bolt stops about a quarter of an inch from closing fully.
This is even though in reloading the brass, I hammer the brass all the way into the Lee die with a plastic hammer. I can tell that driving the brass into the Lee die with the plastic hammer sizes the neck because when I knock them out of the die, the neck area is "shiney". I am beginning to think though that the Lee die does not actually do a full length re-sizing on the cartridge case. And therefore that my fired brass have swollen down towards the base and this keeps them from fully chambering in my gun.
Does anyone know what I am talking about....? Anyone have any wisdom to share about reloading for this cartridge? Thanks
