I am planning on buying a 700 sps and restocking it in a Mcree chassis. Optics are still in the decison phase but will probably go with a Vortex FFP scope. The sps I belive comes with a 1-12 barrel. Will this twist be a problem with the 175's or should I stick with 168's and 155's. Also planning on sending the rifle to APA to have some work done on it. Nothing major just a new bolt knob and a brake. Am I making the right choice?
