Re: remington 700 sendero questions
i wouldnt even change the trigger personaly, id just tune up the one you have.
you can always swap that out.
leupold offers 2 different knob setups. the target knobs have covers, the tacticle knob does not. both do essentialy the same thing. ive always used the target, but to each his own. main thing is get it done.
as for loading, check out some of the many excellant articles on that here. also,send for a sinclair cataloug.
start learning about concentricity gauges, and different presses and dies with names like redding, and other quality types.
meanwhile keep shooting, and save your brass.
