Ruger M77 MKII threads/Build
i am doing my own action blue print on my 7mm rem mag. the threads on the action, is this a standard thread across all manufactures. Can anyone get me the thread info on the action? I plan on facing the action and the lands where the bolt lugs rest and lapping the bolt lugs, then chasing the threads. I am a machinist teaching myself gun smithing.
checked it with my gauge and came up with 1-16 tpi (will try that)
machines i am using
mazak qtn-250 lathe
mazak v510 vertical mill
making own picatinny rails for scope and bipod also.
any suggestions would be much appreciated.

Re: Ruger M77 MKII threads
SWEET!
I'm the oposite, No machines. I'd like to teach myself machining.
Your mesurements sound like they are in the ball park. I couldn't tell you what Ruger threads are, for sure. I deal mostly in ARs.
I'm seriously interested, in picatinney rail for Ruger's with the crazy integral perches. (20MOA)

Ruger M77 / Picatinny rail?
The guys in this other thread are talking about bases for the M77. How close are you on that project? I could be interested.

Re: Ruger M77 MKII threads
BigSkyGP,
IIRC, the picatinny rail mentioned on the thread is for the M77 not the M77 MKII. Someone even commented that it was designed for the pre-integral design ... but not really sure.
brainey64,
IIRC, Coyboy (Jim See) have done quite a bit of Ruger action works.
Check out the Ruger action holding fixture ...

Good luck on your new endeavor!

Re: Ruger M77 MKII threads
1-16 tpi is correct. Not all manufacturers use this thread, but some do. The FN FAL and the Winchester Model 70 use this same thread. I read somewhere that some Sako rifles use 1-16tpi, but I am not sure which models.
