Powder depends- I needed Alliant Steel, and found it for $23/ LB at a local shop- bought two pounds.
Saw H4895 for $26.5/ #. I passed, and everyone knows I like H4895. If I had none, I would have probably bit- but I have some, and some I4895, so I didn't need it that bad.
Primers ? Well, the cheapest around here is usually bimart. They have "jacked" the price to 3.69/100- and you can only buy 100/day ( and they mean it, and they know their local people ) I've been buying 1 tray of small pistol a day, even though I have no use for them. All they seem to carry is CCI. There is a muzzleloading shop here that is very proud of his primers- $60/1000, and he's had them all through the panic. If you needed them, he had them. But you were going to be paying double, or even triple, and no- he does not care. He would sell them to you with a smile- $6 for 100, or $60/1000, your choice.
So, I guess I will pay 3.6 per. I will not pay 6 per, lol.
Bullets ?
Pfft.. I havent bought bullets since my last load of 30 carbine at RMR, I think they worked out to 9c each, pre-panic. They are 11c ea now- still a good price, and I would buy them again. (except I have a mould for that too, now.....muahahahahahahahaha)
