Actually I would be pretty happy to just have an idea where to start. I don't have a case for my Hornady so I did a quick check the old fashioned way with a sharpie and repeated chambering. Interestingly enough it appears that the chamber is throated short and the bullet was only about .005 off when seated at 2.20 as per Barnes specs. I will come back to seating depth later, next week I will try Acc 2520 and TAC to see if I can get better ES and SD then work on seating adjustments. Also I have a new Hornady A65G case in the mail, should be here in a week.
In the past with bolt rifles I have found that Barnes MB's, Sierra SMK's and Nosler CC's all pretty much like a "jump" of around .025 - .035. There are always exceptions of course such my .223 liking the 80 gn SMK jammed hard while the 80.5 Berger in the same rifle needs .075 jump. Still the first order of business is the get the ES below 20 and SD's in the single digits
