FWIW, My Lyman 46th Edition lists a whole bunch of CH shell holders but NOT the # 11. It also doesn't reference any of the rounds Grunt2 mentions, which makes sense under the circumstances! ;-)
You might find that the #11 fits the "early" 7x57 case. The first rounds manufactured had a thinner rim and shallower rim cut. Later rounds had the same standardized head as all others from the same basic case. It may fit the 220 swift as well.
XXCross, Interesting info on the 7X57. I have a supply of OLD .257 brass with the thin rim and shallow extraction groove you described. Always assumed it was from a defective production run. Maybe not. Rob p.s. If anyone want's a sample, or pictures, for their collections, let me know.
RCrosby, Ammo loaded under the label UMC or Rem/UMC will almost certainly have thin rims and a shallow extractor groove. (early European ammo will also)
