I'm on the same track as you guys, awhile back got a 6" octagon barreled 500 Linebaugh, couldn't find any HS-6, checked powder burn rate charts to see VV N105 is a tad slower burning than HS-6, picked 18 grains and put it under a 440gr Keith bullet, 1094 fps over the chrono, i left it be and loaded 50 sticks of brass, what a rush these big revolvers are, recoil is an amazing big slow roll, fun is what it is, no handgun hunter here, but i cant figure what animal in conus or Alaska will stop a 440gr bullets at 1050-1100 fps.
VV N105 can be another medium power/lower pressure load option in these component strangled times, i've had two cans of that powder for years, nice to stumble on a use for it, also have some 530gr hard cast gas check bullets, going to have to think real hard to find a use for them.
