It can be corrected. There's a guy named Neil Jones who does it. My BLR trigger is maybe 4.5 lbs, I keep meaning to send it to him, but it's sort of good enough, so I haven't gotten around to it.
I had him do my 358 Win years ago. I never weighed the trigger upon return but I’d say it’s in the 3 1/2 lb range. Works fine now.
