I can finally follow up on this one. I measured the factory trigger with my spring trigger gauge, and it gave readings between about 4 and 1/8th lbs and nearly 5lbs pull, and every where in between. I thought it felt inconsistent and the gauge agreed.
I installed the 2.5lb Jard trigger and was rewarded with a 1.5lb pull, and no measurable variation, at least on my little spring gauge. It feels great even though it is a full pound lighter than it was supposed to be.
This was on a new #1A in 7-08 Rem with only a 100 rounds through it. The factory trigger may have smoothed up after some time, but it is so nice now I am not looking back.
Needless to say that little #1 really shoots.
Thanks,
Rich
