I Don’t have the pro kit but I do have their Reach Reduction kit in my shadow 2 and it’s a game changer. That with a couple springs I’m at a 5.5 DA and a 2lb SA.
I own the XL7C in 30-06, best rifle I have ever owned as well. Trigger pull is awesome and the bolt is super smooth. Accuracy is amazing! I put a Nikon Prostaff scpoe on it with the realtree APG camo pattern...I leave the weatherby mark V at home
