Now that is bizarre! I just ordered a dozen Tom Fuller flints and the tool to compress the coil mainspring on T-C locks, and they arrived last week, no problem. I was surprised that, while they are advertised as Tom Fuller flints, the package had a different name (it's put away right now and I'm too lazy to dig it out to see who that is).
At the same time, when I was at Walmart last week the muzzle loader display of accoutrements was EMPTY, while just a couple of weeks before that it was full. Now we had a ML deer season from January 2 - 6 which might account for this, but we have had that every year now and it's never hit the store with such an impact. Since reloading materials for cartridge arms seems to be back ordered all over the place this may all be attributed to people starting to hunt during the Covid-19 pandemic; it sure is strange!
