Have first series, Post 64 M70, that doesn't group with commercial ammo, shoot groups within a paper plate but nothing tight.
SAAMI chamber drawing indicates length from bolt face to "leade / throat"
@ 2.725", I have measured actual length @ 2.792, difference of 0.068".
What options to rework this area to "ease" the bullet transition?
Polish that area? or re-barrel???
Thanks for responses.
