I installed a Sharp Shooter Supply trigger on my "new" 300 Win Mag.
Much better than the stock trigger in terms of safety at low pull weights, and offers pretty much the same adjustable features as the Timney trigger I used on my last "sniper" rifle.
The Timney was easier to install, the SSS trigger has more travel (which is a good thing for some shooters). The SSS trigger can be adjusted down to break like a glass rod, but I left maximum engagement (which equates to most trigger travel) for safety.
I like the simplicity of the Timney, but I like the the feel of the SSS just as good.
Bottom line up front? Between Timney and SSS buy the one you can get for cheaper.
