I don't know how good the 280 Ackley Improved will be for Long range , but I just ordered my barrel today. A 7MM #5.5 fluted @27" Kreiger. it will be going on a rem. 700 action, A Boyd's feather-lite thumb-hole stock , with a Shilen trigger and teflon coating on entire metal surfaces. I hope it will be a keeper as this is the first custom rifle I have had built. What do you guys think of my choices?
