Factory ammo is now available for the .416 Chatfield-Taylor (it's quite popular these days.) 'Have one and love it. I always remark that I pity the idiot that steals my guns, as most have no available factory ammo. For those in the know, many Wildcats shine. Some owned were eventually SAAMI'ed (.338-06, .338 A-Sq now .338-378 Wby) and many were not, but I handload, so it's really no big deal. You must really be into guns to own wildcats. The .280 AI seems to be a fav now, but you can buy factory ammo for it anywhere. Nothing in the .30-06 case is "magic," but many are interesting...Love my 257 AI and 757 AI (oh, and the .264-300 WSM created by me!) Have a book on wildcats larger than the biggest city telephone directory...it's fantastic! 'Still working out the bugs on the .458-22 WRM (feeding issues?)
