Looks like your on your way.
I would have the local smith put a new 30" Barrel on your outfit.
Hart, Lilja, Shilen, Kreiger are all good barrels and they are made in the 30" length that I would want if I were doing what you are.
I also would have the barrel tapored to about .950" diameter at the muzzle to reduce some of the weight. A muzzle brake
might be nice also. You will appreciate it if you go on up to 240 Gr bullets. 220s are bad enough in a fairly light rifle.
It sounds like you have everything except the scope (unless I missed that) which I would go with a Leupold LR in the 8 1/2X to 25X and the side wheel focus.
Anyway, your on your way and the next thing is ordering a barrel.
The 30 Cal is the way I would go in the range you want to shoot.
Good Luck and Good Shooting.
