Does anyone have any experience with the new 300 Norma Mag, I'm wondering if it will get a 208gr A-Max up to 3100 to 3200 fps out of a 26-28" barrel. And I'm wondering how it compares to one of the improved versions like the 300Jazz, 300 Hulk, or 30 Nawakwa . . . In terms of case capacity, velocity increase, and ease of feeding. This is to be primarily a hunting rig, so feeding and reliability is important, and I'm wonding if the steep shoulder angle and minimal body taper on the "improved" versions of this cartridge will give me any trouble. I could also use imput on barrel length, I read somewhere that the standard 300 norma mag worked very well in only a 26" barrel . . . is that generally correct? or would I see a significant jump in velocity (or reduced muzzle blast) with a longer barrel? And of course, same barrel length question regarding the improved versions.
