I put a JP trigger in my LR-308T and am very happy with it, it was a huge improvement over the stock trigger, I went with the 4 pound spring. With the JP trigger smallest 5 shot group size to date is .255 at 100 yards with normal being about .6"
I think most would agree that the JP is the best single stage around. I just put in a Geissele though and it is awesome. I was very resistant to two stage triggers until I tried one and they are really good for accurracy.
