for use in a 2A Enfield - what factory hunting round would you suggest, that approximates the pressure of 7.62x51mm?
Shoot the "managed recoil" stuff, assuming you do not handload.
The above links perpetuate the misconception that the .308 Winchester is loaded appreciably hotter than 7.62 military. That is not so. The US mil-spec for 7.62 is 50,000 psi MEASURED IN A CRUSHER GUN. The US Army is not a member of SAAMI and does not use the "CUP" term for crusher gun readings.
Original .308 Winchester pressure spec was 52,000 psi MEASURED IN A CRUSHER GUN before SAAMI adopted the "CUP" term to differentiate between crusher and piezeoelectric gauges.
There is commonly 2000 psi/CUP difference in different lots or even individual rounds of ammunition.
The only real hangup is the longer chamber headspace of the 7.62, meant to accept low grade wartime ammunition in hot dirty automatic weapons. That could give trouble when reloading .308 brass shot in a 7.62 gun. IF you set the shoulder back all the way.
