My advice is to purchase a Sendero,preferably
an older model since the new models with the J bolt are crap(Ask any custom gun maker about the difference between both models.
I have a 1979 Sendero unfluted heavy barrel
in 300WinMag.Bager 20 MOA rail and Bager Max 50 rings,Leupold MK4 10x Mildot scope.The barrel is 29 inches(26inches with a custom 3
inch muzzlebrake,hence 29 inches.)Trigger set at 2.5lbs.Using Federal Gold Match 190 HPBT
this rifle has taken chucks out to about 1100
yds.The whole point being is if you start with a small caliber you'll always want to shoot longer ranges,so buy the big 300.By the
way,With a muzzlebrake recoil is reduced to about a 270 caliber.Of coure this is just my opinion,I may be wrong.
