Re: Savage 340 Barrel Nut
It would be easy with a spanner that fits several size diameters and has a hinged claw. You could make one by drilling a hole in 1/2 inch aluminum stock the same size as the od of the nut.Once you drill the hole you drill and tap for a 5/16x24 thread next to the hole and then cut a slot straight through the threaded portion.Slip over the nut and clamp it up and smack it with a dead blow hammer.I use rosin all over the area that you are clamping on,it will help the wrench grip and not gall the nut.Take a look at the wrench on sss's site for the smooth nut they sell.That way you will understand how to make one.You can have a barrel made from an adams and bennet replacement sporter tube from midway.Sounds like a neat little project.Incidently,your barrel may have had some real old 30-30 cartridges shot through it and they were black powder way back when.30 caliber and 30 grains of black powder in the old days.

Thanks for the reply and tip Joberman.
Re: Savage 340 Barrel Nut
Just FYI - The 30-30 was the 1st. cartridge made from new for smokeless powder. They just carried the naming over from the black powder days.

Re: Savage 340 Barrel Nut
Partially right. It was the first commercial cartridge designed for smokeless but the "30-30" is the name MARLIN gave it (Winchester called it the 30 Winchester Center Fire or "30 WCF" just like they did the 44 WCF, 38 WCF etc.). Marlin didn't want to advertise for Winchester so they carried over the naming from the older parent cartridges for the new fangled one (38-55 and 32-40 which were marketed as Marlin / Ballard cartridges). This is also why Marlin chambered their guns in the 25-36 Marlin instead of the 25-35 Winchester.
Probably pitted from corrosive primed ammo.
e-gunparts.com did have new old stock 340 barrels in 30-30 last time I looked.
Barrel nut wrench for 340
Looked and looked, but couldn't find one. Finally used a pipe wrench. One time, I bought a new nut from Numrich for $6, the second time, I just polished the marks off the old one.
