Only going to continue to go up, gone are the days of $35 to $45 8lb jugs of powder.
Look at all the different powders & primers you use and buy as much as you can afford to.
I wish that I would have bought a hell of a lot more back when I could afford to bulk buy powder & primers to max out hazmat for each.
2A will keep firearms for sale, but ammo & reloading components prices will get so expensive you can't afford ammo to shoot.
See a lot more people buying bp firearms since some shooters are even making their own black powder & damn near every reloader/hobbyist has casting gear to cast bullets.
I do miss seeing the very affordable cva rifle & pistol kits and muzzleloader gear including powder for sale at walmart, target, tg&y, otasco & near every sporting good shop around.
