What is the difference between a Uberti/Cimarron and Winchester chamber

[Black River Johnny]

If there is a difference between the too, as far as haveing to use uberti dies instead of dies for a winchester what is the exact difference? the reason I ask is that I am haveing some trouble with some of my 348 brass getting stuck in the chamber, The exact example is - if I chamber a round and shoot it will extract and then I can easily rechamber the spent case, but some cases go in hard and if I do not fire it, some times it wont extract. now all of these cases have been fireformed and some have not been resized because it seens as if the lyman winchester dies resize them too big. Any help here would be great. Thanks

First of all there is a difference in the chambers and for what it is worth-- and be prepared to pay a few bucks but what I did was send RCBS a fired case actually a couple and had them make me fit to order a Trim and File die and an FL die.  I have never had any problems what so ever.  But as the old saying goes--if you want to dance you got to pay the fidller.

Would the dies for the uberti that C&H makes, fix my problem?
