Whichever will kick butt......lol
I said to myself, self, why do you need a 30BR? Answer, cause if I do not, i will likely no longer shoot score. Hard to shoot against 30's with a 6. Thus to shoot and have a chance at winning the 30 is a must now.
Going to build it as a light so if and when border opens up i may shoot some score across the line.
Twist likely a 17.
Going to switch my original Bat rifle which has won I believe all but maybe 1 group match into the dedicated score rifle.
