i've seen plenty of discussion of people using them.. if nothing else.. they seem to report that they go bang.

as for local cheaper.. I've only ever found 1 thing cheaper locally.. and that happened to be an rcbs reload press.. walmart had it cheaper than midway.. by a bunch surprisingly.. must be a bulk buy issue.

local stores are selling powder 4-8$ higher than online.

buy a few pounds and you made up the hazmat charge right there....
