Thoughts on Ruger M77 Action Potential?

[North River]

Can the factory thin profile M77 tang barrels be threaded?

Also, has anyone tried doing a full length bedding and had good results with improved accuracy? I glass bedded just the action and first couple inches of the barrel on mine. It helped with accuracy, but I’ve heard bedding the entire barrel channel helps these guns a lot.

With a good quality, heavy barrel and a really good bedding job, I’ve found 77s to shoot decent with free floating. But with lighter barrels it has been my experience they improve with slight tip pressure on the barrel. I take electrical tape and add a little to the barrel at the front of the forend to vary contact pressure.

You'll want to measure the diameter at the length you want threaded, but Karl at Kampfeld Customs can add a permanent shoulder to a thin barrel by threading 1/2x28 and attaching a very clean adapter for 5/8 with the appropriate material for a shoulder. He did my Tikka Lite...looks top notch and the threads are perfect and straight.

He said he could also do my Ruger 308 RS if I so choose. It has the ultralight barrel profile and I gave him the diameter, so I imagine yours would be good to go. Per his current pricing, barrels with an OD smaller than .63" are an upcharge from his standard pricing. ADCO can also perform this service.

I don't know if full-length bedding is any better/worse than free floated. I understand the old NULA rifles were fully bedded because the stock materials used were stiffer than the barrel and wouldn't flex under pressure. You could always try the electrical tape trick mentioned above and see if it improves, though accuracy may be subject to forend pressure. I just choose to free-float mine and take that out of the equation.
