I have been getting an itch to build a big target gun for fun (BR style, front rest and rear bag). I’m thinking about a 338 Lapua Mag improved or maybe a 37 XC. Due to the size and performance of these cases, along with my intended use, a big single shot action that has a larger bolt and lugs appeals to me for the strength and safety. I plan to hang a 1.35 or 1.45” barrel on it that can make use of a larger tenon. Does anyone have experience with the newish BAT XL or have other advice and actions I should look into?
