Quick question about an old can of H4350 that's been collecting dust in my cabinet for many years. Now that it's harder and harder to find powder I'm having to resort to using this old powder in my 260 Rem. I believe this powder was stored correctly and has not dried out. Has H4350 changed over the years? This powder looks darker than my newer can of H4350, (what's left of it). I know that new H4350 is now temp insensitive and is one of the extreme powders of Hodgdon. I'm not sure when they started the extreme version of H4350. Attached is a picture. Notice that the can says "New from Hodgdon", LOL. Any comments, answers or profound statements on using this powder. I would of course start low and work up looking for pressure signs. I have written Hodgdon a couple of weeks ago, but have not yet received a reply. Just thought I'd ask before starting up a new load. Thanks!
