Almost impossible to find shells.... You can but they are extremely expensive,.
I was looking through catalog I get and noticed some for sale. Cabela's (http://www.cabelas.com/) sells the .455 ammunition for about 14-15.00 a box. This is, granted, more expensive than the cheapest .45 ammo, but it isn't a bad price at all. Especially considering the quality of the .45 Webley modifications we are seeing out there. Just an idea. I find that a box of 20 is fairly sufficient for any "carry" applications I may run into.
