Boyd....that sure is smokin !! Have you tried any loads with the 168 MK. I have around 100 of them sitting around that I have been using in my 300 Win for "fun" shooting ( to expensive to shoot my NOS Parts up all the time ). I am thinking about using them for break in and fire forming. Still not sure about the scope for the sendero yet...it's either the nikon or the leupold...just can't decide.
