Shooting from a sandbag rest at 50 yards, the best I could do was a 3" group dead center.
I purchased a like new Savage Lee Enfield and took it to the range. It would not group on a 8.5" paper target at 100 yards.
I removed the forened screws, and the forend fell off! It should have been a tight fit. Obviously the bedding was bad when it left the factory, or the wood had dried in the 50 years since.
I bedded the rifle, following guidance in the book "Lee Enfield Rifle" by Major E G B Reynolds.
This brought the groups down to 2.5 MOA at 100 yards. Actually the best groups were fired when the bedding compound still had some give (2.3"), and once it completely hardened, the groups increased to around 3 MOA.
I later center bedded the rifle and found that that was a mistake. Group size did not improve and it was now more sensitive to foreend pressure.
I have examined the chamber of my rifle and saw lots of reamer marks in the throat, and the barrel is closer to a gray color than bright. So I don't think these rifles were built to be tack drivers. I think as long as they went bang, that was good enough.
The best built No4's are the No 4 MKII, and the Long Branch.
