The story of Savage going with the 87gr bullet & slow twist to get that first magic number of 3,000 fps is as old as the cartridge. Would things have been different had Charles Newton not caved to Savage & used the 100gr projectile as he recommended, who knows?
I thought the PRC case was the answer to the 6.5 Needmore. As in needed more velocity.
Actually, Gunwerks got the people at Hornady thinking about it with the colaboration between them on the 7LRM. Gunwerks was looking for a velocity improovement over the 7mm Rem Mag, with inexpensive, readily available brass. Enter the 375 Ruger case necked down.
I don't know much about the SAW, other than the military acronym for Squad Automatic Weapon.
I wonder where proprietary cartridges fit into the mix?
Names & cartridges of Dakota and Lazzeroni can get ones creative juices flowing.
Something like a 6.53- 7.21Tomahawk.
Figure out a way to get Peregrine bullets from South Africa and i'm all ears!
