Question - does Bismuth shot have a shelf-life? Reason I ask is I have a couple of boxes of 'vintage' Bismuth (20 plus yrs old. They are branded "Bismuth" - dark green box with red lettering, mostly 12 ga, 3" #2 and BBs, 10rnds per box). Last time I picked up the boxes it seemed like the shot had turned to a fine powder and/or the shells themselves seemed 'not quite full' as if the shot had condensed. I'd hope this wouldn't be the case with the newer Kent Bismuth.
Curious here too. I had a box of .410 Bi I bought when it first came out, maybe close to 20 years old now. I know the price tag is still on it at $34.99. But wonder if it would deteriorate after that much time.
