Apropos "unmentionables," there has been no new brass available since 2020 for the best one-shot-stop SD revolver-and-rifle round in history, and an FFL-dealer longtime friend tells me this is no accident, that it's part of the federal government's (bi-partisan) plan for forcible civilian disarmament and the reduction of all of us to mandatory pacifism and compulsory victimhood -- that is, to the definitive condition of slavery.
Whether that is also the reason for the percussion-cap shortage, I know not, and neither does he.
Nevertheless -- despite the hitherto-prohibitive fact I live where there's a nine-month rainy season -- I too am acquiring rocklocks, hoping to learn how my British ancestors kept them reliable while exploring, trapping and settling in these regions.
