Re: remington 700 sendero questions
I have the old trigger as well and it breaks fairly light and very crisp. It's very close to my Sako M85 which is set for 2 lb.
By the description of your shooting experiences, it sounds like you have a very accurate rifle. If you work on your techniques, I'm guessing you could tighten things up a bit.
Again, if it was me, I would work with what I have and tweek it a little, like maybe a new trigger, work up a good custom handload, maybe a skim bed job, and work on your shooting techniques. I'm thinking that you should easily get consistant sub .5 MOA results.
When my Sendero burns out and I get a new barrel, I'll get the action blue printed and reciever trued, bolt worked on, trigger, etc. and put another Sendero contour on in a match grade barrel.
Good shooting and keep us posted on your progress.
