You can end up with a decent shooter from CMP. (I'm cross posting on purpose to prod all the new M1 owners to check out the postal match
Winter Warrior 2021-2022 Postal Match for Iron Sight Military Rifles )
This is the International Harvester M1 I received last month from CMP. Slept like crap last night and was a bit groggy this AM, so like a dumbass I grabbed the wrong ammo and only had 7 rounds of Varget + 168 SMK reloads and the last 3 were HXP '77 dog crap ammo:
Shoots pretty good for an out of the box CMP M1, no? I should qualify that a little: I did do the usual match prep, trigger job, stock clearance work, etc.; but there's nothing on/in this rifle that did not come from CMP except for the Mobil 1 grease.
Except for the SMK edge of 10-ring shot at 2:00 that was my bad, all of my reloads and one of the HXP shots were X's. That HXP shot in the 9-ring I'm gonna blame on the HXP. This particular 1977 lot has been crap and regularly throws low flyers, but I bought it cheap in the enblocs a couple years back and nearly all the brass will be OK for reloads. Eventually I'll go back and try shooting again when I remember to bring the right ammo.
