Since my introduction to breech seating bullets in the 32-40 I've used a few different powders. IMR4227 for the most part, some 5744, and more recently AA#9. It has been suggested to me to try 4100 and or Enforcer. I have yet to hear of anyone using powders of a similar burning rate in the Vihtavuori brand. A look at the burning rate chart shows N105, N110, and N120 in the same area of burning rate as the a fore mentioned IMR & AA powders. In my experience with Vihtavuori powders in modern center fire rifles they are of very high quality. Yes they tend to be harder to find and a little more expensive, but have proven worth it in several cases. Would like to hear from anyone that has tried them in the 32-40 or the 25-20SS what your experience / thoughts are.

40rod, Thanks for the reply. #9, 4100 and Enforcer are not to be found in my neck of the woods. Have been told that 300MP is also good. Can't find that either. I'll keep looking.
