Most people over clean thier firearms.
By this I mean too often.
If the rifle shows no sign of degrading load characteristics/ firearm function, dont bother cleaning.

The accuracy I have been getting has just over 1 MOA at 200.
I have shot groups that maintain this level of accuracy out to 400 yards. 1.5-2 MOA out to 600 yards
All with the 311299.(200gr.) IMR4831/4350.
Hornady gaschecks.
Lyman super Molylube
.310" sized
Bullet noses coated with Lee Liquid Allox
Seated firmly into the rifling.

Lots of fun!
