BTW. Nice work on the components. Are you going to Post or PM drawings? :)
The 110 receiver is made out of steel, the Impulse receiver is made out of thin Aluminum that's surrounding the steel barrel extension and barrel.
I wouldn't want to thin those parts to accommodate the large diameter WSM case.
Drawings won't help anyone that doesn't have the machinery and very costly carbide tooling needed to machine heat treated metal.
Not to mention the custom line up jigs needed to make the extension + lug and the expertise to get those jigs to mesh with the machines to create parts with less then 5 thousandths tolerances.
This wasn't plug and play and if I would've known the costly issues we were going to have to overcome before we started, I would've just bought a couple of rifles to get the parts and called it a day.
The factory barrel extension was hand fit to the lug, as the anodizing was removed in some places and it was like that before I shot the hell out of it.
Our parts are made to much closer tolerances and don't need to be hand fit.
That cost me a pretty penny and a lot of sleepless nights to accomplish.
