Yes on 133 and it's $272 per 8lbs at Whiddens.VV133 or Accurate 2230
These are the three I use for cheap stuff. I also use StaBall Match and 8208XBR for precision loads.BLC-2, H335 or Ramshot TAC. None are really cheap anymore, but at least you can find them. BLC-2 is best for heavier bullets. It is my go-to powder for 77 grain SMKs.
….equivalent burn rate propellants.If you want inexpensive powder to load 223 I have bought and load tons of pull down powder from American Reloading. Comes un stock weekly and sells pretty quick bur $160 8lb...
They regularly have BLC2, H335, w748, N133 A2230.....
