With the criterion barrel it sounds more like a CMP/DCM rebarrel than an military one. When the "naveys" were assembled criterion wasnt here yet.Would be interesting to know if its a standard contour, med heavy or full heavy barrel.
My garand in 308 has a 4 groove 1-10 twist med heavy barrel on it made by Douglas. Its a shooter. M852 match ammo in it is a real performer at 600 yds. My rifle is at 2-3 clicks up at 200yds, 300yds is 5-6 clicks up, and 600 is around 18 up this is from memory. For years this was used as a loaner rifle for gents starting out in high power.
I believe hoirnady has a service rifle section in their loading manuals that is also at the correct port pressures.
HAs your rifle been glass bedded, or any other match mods done.
