I have two chrome lined and two stainless barrels.
After years are figuring which likes what ammo the accuracy of the four goes like this.
Most accurate to least.
Stainless 1-8 twist ArmaLite National Match 20"
Chrome lined 1-7 twist LMT 16"
Chrome lined 1-7 twist Colt Match HBAR 20"
Stainless 1-8 twist Unknown 16"
There's more to accuracy than chrome or non chrome lined barrels.
