LRI's inletting work is done with some fairly sophisticated CAD software and use of CNC machining centers. One of very, very few shops able to offer this. Each action is fully rendered along with the barrel. The inlets are created using surfacing tool paths, allowing for a very accurate mirror image footprint of where the barreled action, floor metal, and peripheral hardware reside. Here, I intentionally inflate the cavity size by .05" in all directions as I feel its a better way to bed a gun rather than the paper thin skin bedding that is the norm.
There's one caveat here though. This process is part of our pillar bedding services. I've never offered the inletting work as a stand alone option. I guess we could, but I'd still want the customers barreled action in my hands to ensure it left here. Years ago I did work like this at Dakota Arms for an entry level M97 rifle we were contemplating on offering. It was 1:1.
Happy to help.
