What is the difference if any, in Hodgdon, and IMR powder? Example: Hodgdon 4198, and IMR 4198. Are they exactly the same, or is there some different characteristics. I am going to load for my 45-70.
Even if "exactly the same", you still have to work up loads tobe safe. Even two different lots of H4198 may be slightly different, etc.
