I to shoot a sendero in 300 rum. I was able to do some minor tweaking to my trigger and get the pull down around 3-4 lbs. Timmeny make an after market trigger for the 700 sendero with a pull weight of around 2-4 pounds and a choice of a two or three way safety. My sendero is a down right tack driver but is on the heavy side but that helps to keeps the recoil down to an exceptable level.
