Ah, pelago.... there was a small article written about that VERY subject a year or so ago and I suggest that you ask nicely, of someone with a higher degree of computer skills than me, to reproduce it. I recall that it certainly covers the graunchy trigger pull that you mention.

The trigger pulls of the Enfields should be 1st pull,between 3 and 4 pounds and 2nd pull, between 5 to 6.5 lbs. Don't forget that when you load the trigger tester, it must follow the normal line of the finger that is squeezing the trigger. It'll always be heavier if you test it parallel with the bore
