Hello,
I have both the Ruger and the Sendero and love them both. As far as long distance shooting I have my Sendero, which is .300 Mag instead of 25-06) set up for long distance (1,000 yds.) with a Leopold 6.5-20X50 Target scope, Harris bipod and sling for a total weight of 13-.7 pounds. I also had a trigger job done to make it buttery smooth but breaks like glass at app. 1.5 pounds. It is an AWESOME long range weapon for the bench but definitely not one for packing all day, unless you are into bodybuilding! lol I would highly recommend it but unless it is something brand new the Sendero is not offered in the 25-06 caliber. Unless things have recently changed, it is only offered in the .264 WM, 7mm RM & RUM and .300 WM & RUM.
Hope this helps and good luck...
