I recently inherited a Lee Enfield No4 Mk1 from my father. It was a gun he used in Bisley shooting between 1958 and 1970. The rifle was not fired in the last 35 odd years (before it came to me) but kept fairly well oiled. I now use it for shooting at a club where we are only allowed to shoot with .303 British military rifles as issued. Competitions take place once a month when we shoot from a different distance, starting from 100 metres in January up to 900 metres in September. The competition normally is 3 sighters + 10 shots to count from the prone position in approx 20 minutes. My experience was that I always start well with the non-counting sighters spot on after which the grouping opens up badly - 100 meters 6-8 inch diameter - indicating that something happens when the barrel gets hotter.

I've shown the rifle to a gunsmith who pushed his barrel scope in and showed me that there is some pitting of the rifling present. He ascribes it to the ammo that was used in the old days that caused barrel deterioration of the rifle was not cleaned soon after a shoot. But he says that he does not explain the size of the group. (I must also say that I shoot a lot better with a good rifle 4-6 inch diameter groups 100 metres)

I have noticed that the front wooden cover of the barrel can rattle around the barrel at the front end - and was told that's the way these guns were made. I've also heard that some people have found that the accuracy improves if that movement is removed through either glassbedding or cork bedding or a cork ring packing (terms that are all foreign to me).


The particluar gunsmith (who I happen to know is an excellent gunsmith) says that he tried to pack three No4 Mk1's in his life and only one of them was reasonably successful and therefore does not even try it anymore - saying that it is more of an art than a science to pack these things and he feels that he obviously does not have the touch.

Any advice on where do I start and what do I do ?

I don't think either the bore pitting or the headspace would affect accuracy that way. As you suspect, the problem is what is happening to the barrel as it heats up. I am sure bedding (which I guess is what you call "packing") would help, but it could be that something is happening in some unpredictable way, like the front sight rubbing against the nose cap and raising cane with the barrel vibrations.

Headspace OK, reloads OK, it is definitely a progressive thing as the barrel heats up.

You both confirm my suspicion on the bedding and those two sites on 303's are excellent - a lot of material to work through for this newbie amateur gunsmith but I'm going to do it. I'll publish my results here.

Jim - I'm ignorant about some of the terms (English is not my first language) "nose cap" - is it the metal enclosing the wooden part of the front stock right behind the front sight and "raising cane" - the bottom half of that wood ?

Regards,
Neil.
 
I have an unsporterized No4 mkI that has no packing and the barrel buzzes in the fore stock after each shot.

It is amazingly accurate for what it is.

I had a friend who immigrated from GB and sold me a No4.
After he died, his son was keen to get the rifle from me.
We worked it out.

I have loved this pic since almost the beginning of the WWW taking off:

Proper bedding of the Lee Enfield rifle is something that is not widely understood in the US. One problem is that as the wood ages and dries out, it actually shrinks away from what is previously touched. I suggest that you follow the link and download the Commonwealth Armourers manuals that are available there. Either let your gunsmith read them, or else you may want to try the process yourself.

There is also a wealth of information available there from the forum members, people from all over the world, who enjoy shooting their Lee Enfields.
