Just out of curiosity.

Does anyone know of any other rifling designs other than the normal that has ever been tested for a 30BR ?
The normal would be 3, 4, 5 and 6 groove .308/.300 conventional or canted land designs.

I am hoping that some of our seasoned shooters that were around during the inception of the 30BR may recall any other barrels that were ever tested or used.
 
I haven't seen anything too out of the ordinary...have shot 3 grooves (Lilja), Kostyshyn's, Rock Creek, Kreiger, Bartlein over the years. Fiddled with one .298/.306 'Palma' bore Broughton.

Have wondered if there's anything there with a Marlin style micro groove??? -Al
