WTK: Hand-times at '11' but wrench breaks at 175???

Okay all, figured I need to veritable collective's opinion on this one. Here's the scenario: LMT receiver (29xxx s/n# range), SA barrel that hand-times to 11 (maybe a little past), threads have anti-seize and turn freely with zero binding.

Get the wrench on the receiver and, without the barrel slipping in the vice, I get to twisting. Okay, the GD torque wrench breaks at 175 ft lb, but the sight block is still a decent bit from '12 o'clock.' WTF gives? Do I ditch the torque wrench, grab the big ass breaker bar, and get 'er there? Mind you, I've shaved/sanded the barrel shoulder a bit already, but still this issue. I'm not a novice at this, but somethin' don't be seemin' right. What say the hive? TIA...

If the breech face of the barrel isn't hitting bottom first, I say crank it in.

That's what I was thinking.

I would probably back off and study it before forcing anything.

When I installed a G1 barrel on a LMT DSA receiver (years ago) I had similar situation. Actually torqed it so hard I had difficulty backing barrel off. When I did get barrel off I had to do a wee bit of filing to breach face of barrel which resolved the issue.
