I have a 260ai that is built on a Stevens action. It is bedded into a Bobby Hart Long range stock with pillars installed also. The barrel is a stainless shilen select match barrel that is 26" long. I think it is a varmint taper. I believe it is an 8 twist. I has a rifle basix savage 2 trigger...
As far as triggers go I have a rifle basix Sav2 in one of my rifles and it is sweet. I have it set at about 4oz and love it. So there should be no worries about replacement triggers.
I have the above barrel for sale. It is a small shank and 28" long. I forget the taper though. It looks like a heavy varmint. When I dig out my micrometer I will measure the diameter at the muzzle. It is a good shooter. It keeps 75gr Vmax's in the .3's at 100 pretty easy. Round count is at 480...
