[QUOTE="Alex Wheeler, post: 1881230, member: 101859"] Joel is right, ignition is critical to accuracy. The smoothness of a timed action takes a back seat to accuracy. You can get both if you do it right, but if your not willing to do it right, just deal with the cock on close and keep the firing pin fall where it needs to be. The general rule of thumb is .240" minimum so long as the rest of the design is up to par, as in a full weight spring and guided firing pin. If your dealing with a factory action that has drag or a weak spring, you may need more. This is one of those no free lunch things. To have an ignition that gives your full accuracy potential you need enough fall and spring. It is going to open a little stiffer than something with a weak spring or a shallow cocking cam. Anyone can design an action that feels good to run and goes bang. But theres a reason all the top BR actions have similar ignition specs, because they have to be competitive in the only game that measures group size and have learned the right recipe. [/QUOTE]
