Hey Casing I have a couple questions for you as I am going to be picking up my 280AI, my smith has to pillar bed the stock then it will be shipped to me, I can't wait. I see your using federal 210 primers. Have you ever tried federal 215 primers??? the reason I ask that is I have like 7000 of them and not much money to go buy a whole lot of supplies as I am disabled and unemployed. I had pretty much decided on 140gr accubonds, but was thinking about either IMR 7828 SSC or IMR 4831, but am not sure how temp sensetive those powders are. Heck I still have almost 8lbs of retumbo powder left, not sure what I am going to do with that stuff. With any luck by this time next week I will be putting my jewell trigger in and nightforce rail on and sightron scope. I have seen where some people claim they are using 215 prmers and they work fine and others say they are getting pressure. Mojo the desert is calling my name, am hoping this one will be the most accurate gun I have ever owned and kill many muleys.
