RE: (.308)warbird
Dunno about outshooting another round, but I do know that Lazzeroni which are A+ rifles, are way over priced and ammo availablity is extremely difficult. Unless you mail order the stuff. I'd rather be able to walk into my local gun dealer and buy a quality bullet/caliber right off the shelf.
Why go through the headaches of Lazzeroni when one can get quality Remingtons, Sako's, etc....
Just my opinion.
