Look into what a body die can do . A small base die may be useful if your chambering issue is near the base diameter but I think the issue is chamber length . You can also buy a Redding SB body die if you need it . What you need to do is test where on the case is it too tight ?
Polish a tight case up with fine steel wool and try to chamber it . Don't jam it in too hard just enough to show some marks.
Then look at where it is sticking.
Remember Redding do not recommend you jump at using a body die to resize loaded ammo .
Stunt men don't recommend you jump of a building either but you can jump if you choose to .
