You have done a great job here, and I agree with another post in one of your threads, there is nothing wrong at all with your work.
I have a 338 Win Mag barrel that I have been sitting on for a bit now, and a striker mag and trigger group. I been thinking about using everything to build a long action rifle that is center grip, and over 26", and a barrel of at least 17".
Again, great work, and keep us posted, a 338 RUM sounds interesting, although I would look at a 338-375 Ruger.
