SkullKeeper,Indeed, PacNor will make a barrel chambered in 318WR. Be advised though that the throat will be too short for the COAL of 3.35”. I know because this happened to me. I got Manson to build me a throater to fix the issue and PacNor happily did the work without a charge. I elected to go with a JTL of 60 thousandths and it shoots wonderfuly. The great thing about PacNor is they have an option where you can design your own barrel for a small fee. They will also copy a barrel to spec if you are replacing a barrel for an existing stock.
Love your rifle in 318 WR and appreciate your insights and experience with the cartridge. I have been on-again/off-again on deciding to pursue my own 318 WR project. Your post has provided inspiration but some questions for you, if I may:
I have leaned toward having PacNor chamber and install the barrel. What is the cause of the short throat from them? Could it be the reamer they have on-hand?
Do they now have the necessary tooling the throating issue?
If not, is this a tool that the Manson folks could supply?
Thanks in advance and look forward to your response.
