What twist is the barrel? You'll need to load a 175 or 178 grain bullet to reach out to 1k AND stay sonic. Hard to say if the short barrel will allow the bullets to stay out of the transonic zone which plays havoc with accuracy. I can't comment on the scope as I've never used one. The BC stock is a very good choice but for 1k shooting but if you going with a mag box, the XLR will be the ticket. Ditch the bipod and go with a bench rest and rear bag. YMMV and this is just my humble opinion after learning from my mistakes at 1k.
