using the 100-grain SWC bullet, sized .311, and 5.0 grains of Green Dot powder. I loaded five each in Federal and Winchester cases, just to see if any difference.
The Green Dot gave a nice 'crack' when fired, recoil was almost not there. No velocity readings, didn't set up the Chrony because A: it was already getting hot, B: it was windy, C: I was lazy. I am curious about it, though; these gave a higher point of impact than the Bullseye loads, so obviously higher velocity. Going to have to load some more and run them over the Chrony next chance I get.
I think I'm going to take the .308" Lee sizer I've got and polish it out to .309 or .310. If turns out I still need a .308" for some things, these aren't expensive, and I think sizing these bullets to a bit smaller than .311 might work better.
