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.

Reason: Add to title
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.
