I keep coming back to N340. I've heard elsewhere that in addition to being really clean, it also has very low flash and meters well in a Dillon 550. Can't ask for much more than that (well... decent accuracy too, I guess).
Looking at the load data, it looks like getting close to max I could use N340 to push a 140 gr. JHP to around 1150 fps from a 3" barrel... exactly what I want in my 3" defense tubes. Or back down to min. loading for lighter, daily practice loads.
Seem reasonable, or should I bump a notch to a slower Viht powder (3N37 or N350?) I've also heard that Hodgdon's Longshot is clean and low flash for a good bit less money.
Trish... I can see how Viht powders might sit on a dealer's shelf for a long time... simply because it's expensive stuff which most reloaders probably avoid. I don't really want to spend the extra money myself, if I don't have to. But the Vihta powders sound like they're all very clean, meter well, and low flash... it's not easy to find all those nice properties in a powder. I guess that's why they can get the big bucks for it.
