Already .454 and .451 roundball hard to find. all the following are out (online):
Cabelas, Track of Wolf, Midway, Natchez, Dixie, and all of several others I tried. Gunbroker auction has them still from small suppliers through their 'buy it now'. Apparently Speer and Hornady are buys making other boolits or buyers are starting to hoard .44 cap and ball (as a last resort legal pistol).
Reloading and casting supplies are cheaper to stock up on for folks who are fearful and putting in a supply against future gun laws.
I think I need to decide on fewer basic reloading powders and lay in some.
