Well, to me. I think the rifle is gorgeous....
Going from Bix/Andy TacPro and Anschutz 5098 triggers to a 6 pound long trigger...
Really nice looking wood on this one.
Regarding your trigger, if its a 6 pound long trigger you have something wrong.
It should be a solid 2 stage trigger with a clear first and second stage, if it's one long pull, like a Mosin for example, there's an issue with your trigger.
Your trigger pull in a No4Mk1 or No4Mk1* is directly related to the angle and depth of your trigger guard inlet, which is also related to the pillar which sits under your main screw (aka king screw).
Often where these aren't fitting correctly (or a previous owner was a numpty who doesn't understand 2 stage triggers) you will find washers and all sorts of things packed in to adjust this relationship, none of these "fixes" belong and are either causing problems or masking them.
A bit of a tangent here, over in the states it seems to be a lot of No4's that people own have issues that are much less common in Commonwealth countries, and I would hazard a guess that its a lot to do with the ongoing maintenance and knowledge of armorers around these rifles in the Commonwealth countries that kept ours going a lot cleaner, and maybe the familiarity of soldiers and civilians around the platform, like what would be seen with M1's and 03's in the states.
We hear about a lot of mag issues, stock fit up issues, rifles getting "rim lock" etc, whereas over here they are so commonly used and maintained in competitions its only rifles that haven't been looked after that develop these issues.
Magazine should be matching numbers. a lot are un-numbered. Another tangent i suppose but you see a lot of youtube people and others talking about how these are detachable magazine rifles and you can change mags to reload etc. This is partly responsible for some of the magazine problems seen. These rifles are made to be fed by charger (stripper) clips, not by changing mags (yes i'm aware of the plan of the original design to be issued with a spare) .
The rifle was built and used with its original magazine staying in place. Post war civilian owners have caused most of the mag issues by swapping, modifying and replacing mags.
There's some really good info out there on restoring and maintaining Lee Enfields including No4's, the channel mentioned above talks a lot about the bedding and fitment of wood, which is where the majority of problems can be resolved, the magazine is another.
Once that mag feeds 10 rounds smoothly every time, leave it in!
