I took some 1000 grit wet dry sandpaper and spun the cartridge in my hand and dulled the bullet and neck. then loaded the round and chambered it, at 2.210 the bullet is just touching the rifling. with the dulled bullet the area that touches turns shiny. It is putting very small marks on the bullet. The longer the bullet the more pronounced the marks become. I don't have a problem with the bullet barley touching the lands, that actually may help accuracy with little to no lead jump. But my concern is the cartridge is .035 short of the SAAMI spec, and what is this going to do with pressure spike. Those first rounds I fired had to be jammed in their pretty good.
