This here is the article that sparked the quest......

Oh yeah, rifle being tested is a rather nice 1886 Miroku Winchester 45-70 lever action, scoped of course! My range of velocities with the selected loads should be from about 1100ish FPS up to about 1600ish FPS. If it works out guess I'll have to break out the chronograph for the first time in 20 years, or go buy one of them nifty magneto chronograps that strap on the barrel.
In the never ending quest for a one powder bench (rifle this time) I spent much time analyzing the varous charts and articles on slower powders in straight wall cases like 444 marlin and 4570.....(44 mag loads in 444 marlin give 44 mag performance, slower than normal powders give slightly reduced rifle performance, who'da figgered!)
So, H380 is the choice. Slower to a little slower (generally) than Varget/IMR4064/BL-C2 and other powders commonly listed for the 400g/405g bullets I......
Selected a range of loads from real light to about medium for the noted slightly faster powders.
Lubed and sized a batch of 405g HBFN bullets with my favorite home brewed lube for everything made of lead.
Miked the case heads and marked each one on the inventory sheet so each shot will allow visual exam and measurement.
Loaded the ammo.
Shoved everything in the trunk for a range trip tomorrow.
Will post up my findings, including any kabooms. No Kabooms are anticipated.
