Guys, sorry if this has been covered multiple times but I'm stumped. All the different lettered actions and numbered actions. Here is what I have. I have a model 85 in 300 win mag that is about 5 years old that I want to put a Timney in. Timney only offers 1 trigger for Sako which is described for the A action, L461,L579, and L61. Will this work?
