Have used, 2230, 2230-BR (older powder) and 2230-C (surplus powder and on my last jug of this).
All have a just a slightly different burn rate, but if you would the loads up with the 2230 version you have, will really like the powder.
Also note from the above, when AA releases a power with just a hint of different burn rate, they may still label it 2230, but will given a additional notation as well. The 2230BR burns just a hint slower than the standard 2230, and the 2230-C burns just a hint slower than that the 2230BR. The reason for this, is they get large amount of surplus powder from time to time and if its not dead on for 2230, then it labeled slightly different instead.
So with the the 2230-C with the slowest of the 2230 powders (just a hint faster than 2460), turned to to be just the ticket for M193 Nato loads.
As for the 2230 canister power, will always be same-same from any lot you get.
