Did a project for a Troop of mine. He has a BAS .308 and wasn't happy. Brought it to the house and said.... Make is better..... Make it 6.5....... Mounted a 6.5x47 Lapua as the large caliber and built a switch barrel with a .223 (1-7 twist). Used a separate bolt for the .223..... The darn thing is awesome!!!!!!!!
