I have a Shilen competition model that's several years old in one of my Remington 700s and like it quite well. Initially, I felt like it was too light to be considered really reliable with the stock bolt and cocking piece. It used to follow through unless the bolt was handled very gently. Once I replaced the bolt with one from PT&G and the firing pin assembly with the GreTan model from Brownells, I have found it to be a lot better. It's still light, which is fine with me, but the tendency of following through is gone. I can even smack the butt stock on the floor and it holds. Although I hadn't considered it before, it seems the fine trigger works even better with a more precise bolt assembly.
I changed the bolt because the rifle came as a .220 Swift and I lost interest in that cartridge. I converted it to the .20 Beggs, so I needed a bolt with the PPC bolt face. I learned a lot.
