Got the 150 grain mold today. When I get a chance I'll cast some bullets, load them up and see how they feed in the Winchester.
I'm sure they are nice. I've used Lee molds for many years. I find them to be perfectly serviceable. They heat up quick a drop quality bullets usually with the first or second drop. I do wish they were sized .001-.002" larger for any given caliber to allow me to size down to where I want to be. I've been thinking of some way to possibly lap them to get there.
Beagling results in oblong bullets. If you want a larger bullet, buy a larger mold, or lap the mold. Watch this video.

Cast a few, four actually, of the 150 grain bullets. Loaded this one dummy for setting the seating die and chambered in the Winchester. Can still see where the rifling engages but it closed a lot easier. I'll load a box and see how they do.
