I have an M1 I just inherited from my Dad that needs a barrel since he blew the old one to heck with water damaged ammo. I can get pull off barrels for around $40 but I donít like my odds of a safe head space just slapping a used 30-06 pipe on it. So I priced new and after I picked my cigar up from the floor decided I wonít be doing that any time soon.
So the tight wad in me (which I also got from Dad) got to thinking what about getting a 308 barrel and cutting a correct head spaced 30-06 chamber in it. Now, I know the gas port on a 308 is not the same size so I need to know if its smaller or larger than on the 30-06?? If 308 is smaller then I can just punch it out and be in business.
I have 3 M1s here but all 30-06 and I canít find the gas port size on the web so where are the M1 gurus that know? Is the higher pressure 308 port smaller like I think guys???
