I've been using IMR 4350 in my 280 AI and 30-06, but it's not to be found in west Texas / east New Mexico, nor is AA-4350 or H-4350. What is the alternatives? I need something that behaves similar.
Reloder 19 and Ramshot Hunter should be in the same relative burn rate. Obviously, you'll need to work up a new load from the start charge no matter what new powder you switch to.
If you have been using H4350, try Alliant Reloder-17. The loads are not interchangeable but we have been getting excellent results with RL17: more velocity less pressure equivalent accuracy.
Wow, that would suck. I use more IMR 4350 and Varget than anything. Have you thought about trying online? If you know some people who need powder as well, you can make one big order split the hazmat fee. They'll ship up to so much weight (can't remember what weight) on one hazmat fee.
