Do you have actual knowledge of Defiance building a repeater
action that will support 375 or 408 CT? Their site (price list page) notes the largest as having a .750 bolt, typically what folks are using for 338 LM, max. I know of no other "retail-available" action that is 408 CT capable and a repeater. Snowy Mountain has no bottom metal and in no big rush to close that loop. Xtreme lists one but I find no consistent good feedback on them or their cation - I hope to do some hands on at SHOT. The only other repeater solution seems to go 50 BMG size and see if you can get the manufacturer to build one with a CT bolt face - with "standard" multi-unit builds seems most actions are built all one size per setup and a one-off bolt seems unlikely.
