Thanks, Steve. Experience makes me feel better about it. I guess I'm just a little put off by looking at different manuals and finding such a difference in load data.
I even subscribe to Load Data .com and found a large amount of discrepancy between 240 gr. bullets. Large variations, with the same specifications. Makes me a little uncomfortable when I get so many different results.
It was a whole lot easier loading the .45acp with Red Dot and then loading 12ga with Red Dot. One powder made it much easier. The .44 Mag and 2400 seems to be a great combo, but unfortunately I just spent around $50-$60 on H-110 that I may not be able to return.
I'll try it and see what happens - look for the obvious over-pressure signs, etc....
