I'm newish to centerfire rifle shooting (160 rounds down the tube) and have been shooting a Remington 700 AAC-SD on a Mcree's Precision chassis with an SWFA SS HD 5-20 on top. What accuracy should I be expecting with SW Ammo 175's SMKs or FGMM 168 SMKs? I've been shooting about 1-1.5 MOA, though I've been hearing people say they can get down to about .75 MOA or so.
