Ive been looking for H4198 powder for a while now for my SML. I have a little left that I use for loading a few CF cartridges. I was doing some research and found out that Hodgdon makes borh H4198 and IMR4198 and uses the old H4198 formulation for both. So they are now the newer canisters are interchangeable!
CORRECTION: My information from another site was incorrect. These powders are NOT the same. I spoke directly with a Hodgdon representative this morning and got the information first hand. Continue to use the different data listed for both powders.
