Funny tidbit about the current market.I scoured the internet for Trail Boss powder but was unlucky.
Bought 1000 .224 55gr FMJ bullets.
Now that my 300 blackout brass is cleaned, need to work up some loads.
Viht N32C is similar to Trail Boss (might be a good alternative for you) as a bulky powder good for CAS loads.
Powder Valley had some last night and it's my current hobby to find powder and primers even though I don't need anything.
Put 12 in my cart but only 9 in stock. Few minutes later down to 5. Few minutes later 0 left.
I think people are buying anything available just to have something.
Seen similar with powders geared toward 50 BMG and shotgun powders. Powders not really any good for most cartridges are going faster than they should.
*edit to add: If you miss powder somewhere look at other sites. Shipments seem to come in everywhere about the same time of the same powders.
