Last week I ordered 5 boxes of Hornady .454 round balls from Track of the Wolf. I got my order today, but only 1 box, with the rest cancelled, with a note that they cannot backorder balls.
So I checked out Midway. Hornady .454s are gone, no backorder. They did have Speer in stock so I ordered 10 boxes at $9.99 each.
That should keep me set for a while. I have a Lee .454 ball mold but it's either oversize or the alloy I used last time has some tin in it, because the balls dropped at .456 - .457. That's OK for my Ruger Old Army but unnecessarily hard to load in my Remingtons and Rogers & Spencer.
The online sources for black powder that I've checked have been depleted. I still have a decent supply from a bulk order from several years back.
Percussion caps have also been difficult to buy in the past couple of months. I was able to get a 2,500 count box of RWS #107+ caps last week from Midway, so I'm set for a while. Midway is now out of stock for all caps.
I'm still waiting to receive the percussion cap maker that I ordered at the start of the month from 22LRreloader.com.
