I've got an email in to Jim this morning, but thought I would query the forum to see if I'm missing anything...

Got a 260 Rem CBI tube & SS recoil lug this week from Northland Shooters Supply for my first true "build". Last week I did my first swap, removing a 204 barrel from a 12FV and replacing it with a factory takeoff 223 barrel from another 12FV - swap went well, it headspaced properly, and I can't wait to shoot it.

When I attempted to install the barrel on a 110 action this morning, I noticed that when I screw the barrel nut on the new CBI barrel that it stops when the "top" of the barrel nut reaches the end of the barrel threads, whereas on all 3 Savage barrels (both 12FV and the removed .270 barrel from the donor rifle) the "top" of the barrel nut goes approx. 0.4" beyond the end of the threads.

Using both the thicker NSS recoil lug and the OE Savage lug, I cannot get the barrel to headspace - the action contacts the recoil lug & barrel nut before the bolt contacts the go-gauge.

Basically, with the barrel nut screwed all the way on my Savage barrels I have approx. 1.1" of threads showing between the bottom of the barrel nut and the end of the threads; on the CBI barrel with the nut stopping earlier I only have about 0.7" of threads.

Suggestions?
