Should there be any or very minimal wear on the part of the cocking piece(bottom) that makes the firing pin move forward. I see some wear on mine,could this be causing vertical in a group? Thanks for your time!!!

Could you post a picture and describe your action and how much vertical you are getting? - nhk

I am not savvy enough to to post pictures and really I am just concerned that this issue may be causing some vertical in my last testing of loads and I do realize that vertical can come from a number of things. It is a stolle f-class panda action and the piece showing wear would be the piece that is grabbed by the tool that we use to remove the firing pin from the bolt ,it has a scuff (smooth) on this piece which is the piece that fires forward to make trigger fire.I have seen others that have these marks and have seen actions that don't. I guess that a shim to lower trigger hanger might solve this, but I am just asking if this is common and should worry about it or not. Thanks for your time!!!

If the cocking piece is dragging the trigger top you for sure will have
accuracy problems. If it is a standard Kelbly cocking piece I doubt if there is any
wear. If in doubt on this call them and talk to Tom Griffin.
Some newer triggers are not exactly perfect in critical dimensions so there could
possibly be problems in trigger bar fall but the bar should drop far
enough to not drag on the bolt cocking piece.
Unless you have serious trigger problems that do not allow the trigger bar to drop there should be ample clearance between the two. You can easily check that with the bolt removed. Just press down on the trigger bar and pull the trigger to see how far it drops.

Thanks Jerry for the info. I did what you said and while pulling the trigger shoe it would only move down maybe .015,so I removed the trigger and put the original trigger that came with action back into the rifle and could visually see that it sat lower visually. I had some issue's with the original trigger that were corrected (hopefully) by the designer.I put this new trigger(most popular) in while other one was being serviced,however I kept getting vertical groups and 4 ea cutting and a flyer that should not have been but as you know things of this sort drive you crazy . Now one more question,do you think that the wear on the cocking piece should be corrected? I guess I should call Tom Griffin and ask. Thanks You Kindly for your time!!

He would have to see it to pass judgment. IMO if the wear is a galled surface and it is on the engagement surface it would need fixing (stoning probably). If the wear is just a light scuff and on the bottom of the cocking piece it will probably not matter. If it is on the bottom you might polish it with some 280 wet-or-dry by placing the wet-or-dry on a piece of glass and work the cocking piece across it carefully.

It is a very smoothe scuff and off to the side on the bottom and it looks as though it was polished as if you would polish aluminum. I did get out to shoot it yesterday and I confirmed that it indeed was causing me accuracy problems.I shot 17 shots and the trigger was excellent,so the service work on it was corrected.As long as it continues to maintain its accuracy level I will probably wait until the season is over to have it looked at.Once again Jerry thanks for you time!!
