Frozen nipple in ROA

Pinpoint heat on the nipple only. The metal has nowhere to expand except in length, and when it cools it shrinks a minuscule amount. Then use Kroil penetrating oil on both ends, let it sit for a day or two, and give it another try.
 
proof in the puddin'

I shot the Ruger with the Tesos in place and it worked great. Why on earth did Ruger go to hex nipples?
 
Nipples and nipple wrenches for C&Bs only have two bearing surfaces. When the ROA was developed, it was thought that having six bearing surfaces would eliminate the broken wrench/stripped nipple problem and allow more torque to be applied in case of a stuck nipple.

I guess the jury is still out on that one. :p
