How about a .308 Chassis Pistol?
Remington broke ground on the concept of a handgun with the heart of a bolt-action rifle back in the 1960s with the XP-100, long before there was such a thing as the TC Encore or similar designs.
Flash forward to this year and the company has both the 40-XP, which is just another name for the XP-100, as well as the more interesting (and obtainable) Model 700 Chassis Pistol.
Chambered in 300 Blackout, .223 Remington and .308 Winchester with an overall length of less than 22-inches, these bolt pistols make great bench guns or, after a Form 1, coupled with a stock, decent but rugged glass, and a heavy can (they are suppressor-ready) to give you a great brush gun or backpack gun that can still thump out at distance.
