"Okay, i won't worry about the unburnt powder then, if it seems to be normal."
Whoa, wait a minute.
I don't concider unburnt 2400 powder normal and I've literally sent tens of thousands of .44 Magnum bullets down range with 2400 in metalic silhouette matches and required practice for those matches. I tried 296 a few times, but always came back to good old 2400. In full house .44 Magum loads, 2400 always burned clean for me and gave me the necessary oomph to tip over those 200 meter rams.
You might try, as others have suggested, a tighter crimp. But if it were I, I'd go to magnum primers, specifically CCI Large Pistol Magnum primers - those are what I've always used to ignite 2400. I know, I know, there's a heck of a lot of debate about whether or not magnum primers are necessary with 2400 powder. Heck, I even have a book or two around here in which uncle Elmer himself wrote about using standard primers with 2400 powder. All I can say is, I've never noticed much, if any, unburned 2400 powder in magnum handgun loads. But I've always used magnum primers to ignite it.
Remember - if you're up near maximum pressures in your .41 Magnum with standard primers and you switch to magnum primers, back off on your powder charges a bit. You can work back up later.
All that said, I'm a fairly new .41 Magnum fan. But I've been loading for the two I have for a few years now, so I'm not totally ignorant about feeding them. Actually though, for full house .41 Magnum loads, I prefer Hodgdon's Lil'Gun powder and Winchester Large Pistol primers. As you probably know, WLP primers are for either "standard or magnum" loads - at least that's what it says on the boxes.
I'm putting near maximum listed charges of Lil'Gun and WLP primers behind 250-grain WFNGC bullets from Cast Performance for a little better than 1300fps (honest, chronographed) from a 4" Taurus. That Taurus .41 Magnum is my backpacking gun and I suspect those .41 caliber, 250-grain WFNGC bullets at 1300fps + would get me out of trouble with any large animal I'm likely to encounter in the lower 48 states. It seems like they'd work well for hunting too, at least for animals up to and including the size of mule deer.
