I am still new here so I try not to pipe in to much but I am getting my first magnum rifle at Christmas. Its a Weatherby Vanguard in 300 Wby. Mag. I am no stranger to guns and shooting. I have many guns just standard calibers and I also do my own handloading which I will do for the 300. I know that freebore helps you to gain velocity without raising the pressure through the first inch or so of the barrel not having any rifling. My questions is does freebore help much and can I still adjust my C.O.A.L. to gain accuracy?
