Not going to argue the point but you are wrong. Remington's 308W have a long free bore and it is not per SAAMI. Try and load a 168 SMK 0.010" off the lands in a 700 and only the boat tail would be in the case mouth. No, it is not just my rifle. Those of us who reload for this rifle are familiar with this.That's 5.56 Nato vs 223 Remington chamber....not 308 Winchester with the long throat on the military chamber for their longer 62 gr bullets over the orginial 55 gr fmj.
All sporting arms manufacturers use SAMMI finish reamers.
That's the idea to standardize all sporting arms so all the ammo will fit all the mass produced 308s.
Gunsmiths can change that on individual rifles like Ackley improved, but all Winchester, Savage, Remington 308s should be very close to identical.
