Colorado, I have added a couple of steps to my reloading [either new or resized brass].
Use the Lyman M die after resizing or first step with new brass. it makes seating a snap and seems to eliminate the crinkled neck issue.
I also use a Lee Factory Crimp die as my last step putting a light crimp on the round.
As I mentioned in my first post the results for me are .5 to .75 inch groups at 100 yards with a 60 year old Winchester model 43. { Shooter is 60 as well}
