Why not more attention given to the NAS3 cases and their advantages?

Maybe I'm just misunderstanding what you are trying to say, but most folks using these cases aren't using less powder; they are using more, since the cases hold more.

Cases are thin walled allowing for a larger volume along with a stronger alloy for the higher pressures.

Oh yeah, I guess I wasn’t real clear on that, I mean getting a 6 arc or GT compared to a 6 creedmore, 7 BC compared to a 7 PRC, 308 to a 30-06, etc.


I have a dream, a day where a 16” 6mm Arc has the muzzle velocity of a 24” 6mm creedmore.;)
 
Initial tests with the 49gr of Varget looked pretty good. Test 49.5gr and 50gr and saw no pressure, if I really wanted to squeeze out more velocity I think I could but think Im happy with the 49gr of Varget for now.
