Been reading posts on the sidelines taking in the wealth of knowledge and finally making my first post. I’m getting ready to purchase a new 300 win mag encore barrel from MGM. Barrel length will be 26” 1-8 twist with a muzzle break. Looking at running the 215 Berger hybrid. I have two questions: am I limited to the heavies with that twist rate? Will the 3.700 coal be to much in that barrel? Thanks for any and all help, it’s greatly appreciated.
