Welcome Flying, great to see you are considering a DR in 22 Hornet, a great little cartridge. It must be remembered however that a lot of the work that goes into making a mono-block is in the work holding fixtures that are required to hold the work during machining. These fixtures normally have to be as accurately made as the part itself and have to hold the part firmly so that reasonable sized cuts can be made other wise there is no point in using CNC. As you machine away more material fixtures become more important especially once you remove the flat sides when cutting scollops and radii. Jigs and fixture is a very important arm of tool making and can be quite challenging to do properly. Writing the program is quite often the easy part especially if you have access to 3D scanners or co-ordinate measuring machines where the part can be reverse engineered. Holding it can often be more difficult.
