What range were those groups shot at?  

Was that a typo on the second stage pull weight of 1.25 lbs? M1A match trigger minimum weight is 4.5 lbs.  I would be nervous taking a No. 4 trigger down to 1.25 lbs, tho I have heard of someone else doing that.  I have gone as low as 3.5 lbs, but found I could easily pull straight through to second stage not intentionally.  For reference, here in the US, vintage military rifle match rules for bolt rifles is 3.5 lbs and 4.5 for semi-auto. These have more to do with safety margins than anything else.

i had two b8t they were not on no4s , one was on a Cno7 that went to an enfield collector in achedemia recruiting , the other was a charnwood conversion 762x51 

Now to answer the inquisition! 

The entire trigger pull combined weight between the 2 stages reads ave at 3lbs, 10oz. I was focusing on the 2nd stage weight after pulling through the first stage. It feels like my other single stage 1.5lbs triggers. The cocking piece does not move through the 1st stage, and the trigger is very predictable as I hit the second stage wall. Yes, this is a rifle that needs a notice to a new or different shooter, because they could just blast through both stages unexpectedly if they are used to the stock Enfield trigger. Luckily for me I don't have others firing my guns very often. Even so, all my rifles are set to break light. 

I've drop tested the heck outta the trigger numerous times and shot in 17 F. weather with cold fingers and didn't have any premature firings. 

The groups I posted were shot at 50yds bagged up. The sight picture is much better at that range and if something is off at 50yds, then it's a definite no go for anything further. This was a POI test/observation between Remington and Winchester cases using identical components other than brass. WIN hits lower than REM for some reason only harmonics can explain. (POI at 50yds for a 200yds zero needs to hit roughly 3/4" high) 

This Burris is a shotgun/muzzleloader scope which I paid $110 on sale about 15-18yrs ago. I don't think the thing tracks all that well with zero changes. It's also a very thick reticle. Thinking about upgrading to a 3-9 or 10X scope that will look decent on the rifle. Open to suggestions on that. 

@britrifles or anyone else who knows, I notice AA2520 loads are vertically stringing whereas shot back to back, the N540 and Varget are printing regular cone of fire groups. Maybe the AA2520 is causing a different recoil impulse? Making the barrel bounce off the front lower & inner handquard? 

Some loads will string rounds vertically.  I had that that problem when I tried the Sierra 180 gr PH bullet.  I moved on once I found the 174 SMK shot so well with Re15, IMR 4064 and Varget.  I’ve not tried AA2520 in the No. 4 but shot a lot of it in my ARs and got very good accuracy with it. Some load tuning might resolve the problem. 

Groups look pretty good for 50 yards.  Shot off the bench with scope, these rifles should get down to 1 to 1.5 MOA with a tuned handload.  

The CMP also recently introduced a new class of Vintage Sniper Rifle, 1954-1976.  The L42A1 is the only British Sniper Rifle allowed, but these are quite rare in the US. Weaver K3 or K4 is allowed as a substitute for the No. 32 scope.  I suspect matches in this class will be won by X ring count. 

we also have a wealth of information on enfields that if your patient you will acquire from these threads , some direct others from looking back in our history , its a great site if you want to learn of one of the more complicated areas of military history weapons
