Pathfinder45, where are you getting the Norma 205 powder?
According to this chart, IMR-4451 is right after IMR-4350 in burning rate, so slightly slower than IMR-4350I recognize that burning rates are not absolute, but relative, and may even change to some degree, depending on the lot produced. But the relative rates at least give one some sense of where they stand in relation to each other.
For example, Lyman 50th Ed lists 127 powders from "fastest" to "slowest." Bullseye is 4/127. IMR 4350 is 101/127; H-4350 is 102/127 and H-4831 is 111/127.
Do those of you who use IMR 4451 have any idea where it might be placed in the burning rate?
Norma N-205 was discontinued decades ago. I found mine at the gunshow and bought a couple of cans from a guy that had several clean, un-opened, well-kept cans of it. I had read a long time ago that it was a good 270 powder, so I thought I'd give it a try. Well, after trying it, I kick myself for not buying all of it! And the guy only wanted $8 a can...what a fool I was! It is just the cat's meow in my 270. On the lucky occasion I have found a little more here and there, but only at gunshows.Pathfinder45, where are you getting the Norma 205 powder?
