The reason I doubted that you even owned an A-bolt was that you responded with, "My Sako's break like glass and I pay little, if any, attention to the weight of the trigger." Why wouldn't you relate something about your A-bolt's trigger as that would have been far more relevant than your Sakos?
And then, "Edited to add: Oh, I've never been to one, but am willing to bet when you walk the line of a 1000 yard match you're not likely to find many off the shelf Browning A-bolts with Timney triggers punching holes in paper."
And while I think that it's obvious that A-bolts aren't crowding the lines at Wimbledon, I don't think that you're going to find many off-the-shelf rifles at all, nor off the shelf stiff triggers I might add.
The A-bolt trigger is a good trigger, and maybe fine with a stiff spring for many. I'm not one of those and find it a great trigger with a lighter spring. I posted information about making it better and you objected to that (so don't lighten yours then).
If you want to make a reasoned case against a 1.5lb trigger then go ahead. Your several posts in without even beginning to build a case...
