Glad your happy with your No4

I have been a fan of the .303 and the Le Enfield rifles for many years although I personally prefer the more rounded shape of the earlier models I do have at present a sporterised No4 Mk1/2.
The barrels on the No4's made during WW2 can vary in bore dimensions, it was difficult to keep quality whilst being bombed

after all even skilled men cannot account for the whole place jumping about with the blast of bombs falling and detonating.
Most owners try to find out what their bore measures as it helps in reloading especially if cast bullets are to be used and the .303 can be very good with cast bullets
No doubt the No4 has the beter sights unless you fit Target sights that is and scopes can make a big difference. Have not fitted one to mine yet despite having the mounts and the action beign drilled and tapped by the firm who converted it to sporter configuration and here it is.
Oh that awful ruber recoil pad has been replaced with a nice Ribbed rubberised vintage BSA one
