I have a set of RCBS .455 Colt dies. Unfortunately I also have a supply of .455 Webley cases that of course are shorter than the .455 Colt cases. With the set I have I cannot crimp the cases. Lee indicates they have a crimping die for the .455 Webley BUT the part is also for the .45ACP which lead me to believe it won't work. Have any of you guys loaded these cases and either no where a guy can pick up a crimping die for the .455 Webley case or of a work around?
