Thanks for that! I found this:
Gunsmith Notes, Ruger 77/22 Setback and crown L.R, .22 Magnum and .17 HMR:
CPC headspace gages barreled action upon arrival, noting any changes to be made. Setback breech by .175, cuts shank for SAAMI minimum headspace. The newly cut shank area is left larger fitting the receiver hole with a line to line fit stabilizing the barrel in the receiver. A reamer pilot is fit to the exact bore size then hand bolt match chamber reamed concentric with bore. Chamber is hand polished, bore is hand lapped, a new lock down spacer is locktited in barrel's V cut to insure proper tightening. Extractor slots are recut. Muzzle end bore is indicated within .0002, a new 11° recessed target crown is cut for accuracy. Bolt halves tightened. CPC measures the gap between the bolt halves, grinds and installs a pin that tightens the halves. Tested to be a excellent reducer of flyers and tends to round out target groups. If rifle is shooting low, customer should note this so we can adjust.
Doesn't specifically mention 77/22V but I don't know why it wouldn't work there too. It sounds like what my 77/22 needs, as I'm pretty sure its accuracy problem is caused by a "casual" chamber. I might have to contact him about doing this for me.
Thanks again!
