I am set and ready to start buying stuff for a build. Need help making my mind up. First is the chambering. I am leaning toward the 6.5 Creedmoor but also considering the 260 Rem. Convince me which to go with. I have heard if reloading go 260 if not go 6.5, true? Ok. Second is the action/donor gun. I have been able to find 11 trophy hunter XP Left Handed new for $480. Is their benefits to starting with an FLV or LRP or other? The scope, stock and barrel will almost immediately be sold. The trophy hunter XP is a bottom bolt release with a DBM, any drawbacks to this? Such as chassis later? Need your guy opinions!!!
