Grampas 303?

Looking to learn about my grampas 303 and was told this is the place. No 4 mk 1 Ser# P291xxA England N19 with a crown under it. R something F stamped on wrist, looks like a C.
1 something 42 also on wrist. 2 lands and 2 grooves.
Its been sporterized. When cleaning there is a spot near the end of the barrel that the brush pushes through real easy, almost like there is a bulge. Then it gets tight again.
Some ammo I reload hits 3 shots in 10 inches as it is. Wall hanger or keep trying.

The serial number P291xxA is consistent with the number block assigned to the Royal Ordnance Factory (Fazakerley) in England, The "R" something "F" on the left butt socket is "ROF" for Royal Ordnance Factory. The 42 is the year - 1942.

When you say its has been "sporterized" has the barrel been cut back or are the bayonet lugs still present? Finding the parts for the No.4 rifle are relatively easy but if the metal has been modified in any way, you are best leaving it as it is.

Based on being your grandfather's rifle, it must have great personal value to you.

I would personally restore it to original configuration if the metal work is not modified

What you have in your barrel, without any shadow of doubt whatsoever, is a bulge............ That means that the barrel is effectively scrap.

But not quite worthless because if it's a bulge at the muzzle but otherwise perfect elsewhere, then you or someone handy with a lathe can turn it into a passable replacement for a shot-out No5 rifle barrel

Thanks for the replys. The barrel is still original, with the lugs. I even have the bayonet. The only wood left is under the action, like other sporterized enfields. There is a funny pin with a clip attached for the sling and the pin goes in and touches the bottom of the barrel.
I will continue to see if I can get it to shoot half decent. If not it will just be a memento of him.
I ordered a 314 lee resizing die because the barrel slugged out to 316 to the bottom of the grooves. I might just have to buy .314 dia bullets. I don't give up easy.

Here's a few links where No.4 parts are available from in the USA. One of the Canadian guys will have to give you the best sources for up there:
