Bighorn origin and proof prefit than stock/chassis of your choice is hard to beat for the money. Front Range Precision will cut you a great deal on the stuff.
My father has ordered three Bighorn actions from him and a few barrels as well and his Proof 6.5 prefit is shooting one hole groups and we haven’t even done any load workup on it.
I talked my wife in to getting me the Origin as a Christmas gift. Now I need to figure out what caliber I want to build and then think about my barrel. I've already got a TT Diamond ready to go and an MPA chassis.
