I am thinking about building a 6x45 on a Savage action with a Shilen barrel and was wondering if anyone had real life experience/recommendations for the twist. I am planning on using the barrel mainly for varmint and occasionally larger game. I would like to shoot 70 to 80 grain varmint bullets the majority of the time, but would like to be able to shoot 85 to 90 grain bullet as well. My 243 really likes Hornady 87 grain V-max’s and some crossover would be nice. I am leaning towards a 1 in 10”, but any advice would be greatly appreciated. Thanks
