I just wanted to share this, there will be improvements made on current actions with some things still coming in the future from Jim. The benefits of the new design are, reduced drag on the firing pin and better shroud alignment, adding to accuracy. The new cocking ramp geometry will reduce bolt lift. With the reduction in drag a lighter firing pin spring may be feasible without accuracy loss. I think we will see a lighter spring in development soon, but you can clip the factory to achieve 21lbs. in the cocked position and be just fine in my opinion. Firing pin fall has not been sacrificed with these changes.

Here is a picture of the shrouds and firing pin design we have been using for a few years now along side our new Shroud and firing pin design. Alex Wheeler and I have been working on the shroud design for about 2 years trying to refine many features in the shroud. Alex proposed that I make the long nose with threads on the end and to change the cocking cam in my bolt. Both of use have been experimenting with both items and have been able to get easier bolt lift with our strong springs. The radius of the cocking cam at top of lift has been increased 8 fold to make smoother transition from the lift portion of the cam to the neutral portion of the cam. It makes a big difference in lift. The inside rear of the shroud has been back bored to provide less friction against the cocking piece during firing pin fall. We also are changing the shape of the firing pin nose as more and more use of our actions gravitate away from short range BR to more long range disciplines.
our actions have been extremely successful and these changes are not addressing issues or problems but are aimed at making an excellent product even better. We may also incorporate the wavy CP slot in the shroud that I learned about when Speedy posted about that last week. It would also reduce friction as he stated.
