Nice work on the tool.
I think it was mac1911 who mentioned ~30 shots or so to settle in after reassembly. Seemed to be about right based on last time I had mine apart.
Yes some settling shots are always needed in my rifles.
I don't take my rifles out of the action unless they are broken or get wet. I do a yearly inspection.
If I don't see anything concerning back in the gun socks that have rust inhibitor impregnated in them.
Plus I put these in my safe..

A few points for accuracy
Check rear hand guard , you should be able to get a business card in between the receiver and the wood.
Front handguard should have a touch of play after gas cylinder is installed.
Gas cylinder right. No left to right movement. You can peen the top spline on the barrel....once you get it right leave it alone. No reason to remove until something brakes.
Trigger job..... directions are over on CMP forums. Simple easy and it works. Just go slow and a little goes a long way.
Good crown.....if the crown is rough so will your groups
Consistency from a M1 can be tough remember these where battle rifles built in mass amounts and have the ability to swap parts in the field if needed.
The ammo of the time was Good enough for GI at 4moa . If you read up on the testing they use a median average which can let even worse ammo get through to a certain percentage...same as the rifles.M1 where at 4% IIRC
Also I found my rifles don't like a "sled" type of rest. They will shoot better with a front rest just behind the sling swivel and rear bag.
I still see people rest the front handguard/gas cylinder on the rest or bags.
So if you can get your 60-80 year old rifle shooting 4 moa-ish with HXP your doing well. My build with new Criterion barrel is a 2moa rifle with reloads from supported position...that's the best consistently. I pulled a few 1.6" 8 shot groups. As I,mentioned a few times minute of black is my standard.... for me and my rifles. SR 1 target at 100 yards the black bull is 6 moa.
Accuracy standard for the M1 is 1.77" group at 1000" INCHES.
