Privi- the best way to get a lot of the wildcats is to make them yourself. Simply run a .410" to .416" expander into a .338 case and you have your .416 Taylor. The expander button from a .41 Mag die set will work. Same idea can be used to make the host of wildcats on the .30/06 case, to .40 cal. The Improved Wildcats would be more difficult, of course, without a rifle in at least one of the '06's Improved chambers from .25/06IMP to .400 Whelen IMP. Then, simple necking makes the case. A good capacity Dead-Die Box helps, of course.
