a Jewell (the best and most expensive)
[/ QUOTE ]
I'm about as far from being a competent smith as you can get, but from what I've read Jewell may have a reputation for being the best BR trigger, but it's far from optimal for LRH, tactical and certainly in the range he's looking for ( 24 ox ).
Kirby has done trigger jobs on 6 guns for me (four rem 700's and two A-bolts) - all around 24 oz. I'm more than delighted with the triggers that came back (most were over 100 oz when I sent them).
For off hand, bi-pod, tree rest - a trigger job is the biggest improvement most folks can make to improve accuracy. (IMAO).
