I may rebarrel if it doesn't group this time.
I too picked up used Sendero in 7STW not long ago.The bore looked good with my old eyes.The guy played with the trigger, it is incosistent in pull weight and creep.
I found that mine does not need to be loaded close to the lands. It shoots best ot 3.600 COL.With RL25 and 140 bts the group came together between 80.0 and 81.0 with .412 the best.
My next outing I'm going the shoot 80 to 81 in .2 increments to fine tune what it likes.
Some other bros reported that RL25 was good and I could find some. SO that is pretty much all I have tried.
