Our shooting sports has been getting price gouged for the last couple of years, and I'm talking all aspects of the shooting sports, not just muzzle loading. Shortages of most all shooting related loading components and fixed ammunition has become ridiculous. I call this time in history, the paranoid times do to the, hoarders, survivalist pepper's, ammo scalpers / gougers, and who knows what else?
Now if there is one possible bright spot in all this, it may very well be that all those that were sold on how great those "modern in-line muzzle loaders" are/were,,, well, without being able to get that, rifle or pistol primer, or 209 primer, or a cap, to set off their fake powder,,, they may very well understand the value of a traditional flintlock if they want to continue their hunting and/or recreational muzzle loading shooting?
