ENID, if you can't find a real pair of snap caps for your 450 No2 you can make your own by useing a pair of your empty brass cases. Drill the primer pockets out to the proper diameter to accept the 38 spcl, or 357Mag A-Zoom snap caps flush with the base of the case. Glue in the pistol snap caps, then fill the case with fluid steel, or bedding compound. Then cut the finished case off just rear of the shoulder, with a hacksaw! Drop them in your brass polisher, and they will shine like factory made snap caps, with the proper headstamp!

This isn't my idea, as it has been done for many years before a lot of snap caps were available in the USA!
