So far the combo is panning out. The factory barrel is 22" and the ST-10 is performing perfectly.
The range trip consisted of trying a new load combo and comparing it against some factory loads (168 FGMM & Remington 168 Match ammo). I have some 175SMK's to get loaded and try out though.
I just put the adjustable HTG on this last week and today was my first outing with it. She was wearing an adjuatable HS Precision but after putting a McM HTG on my wifes rifle I knew at that point I wanted to restock mine.
