What difference does it / they make

I'm sure no expert. In my experience I've had the notched cocking piece lock up some of the commercial after market triggers. I've had the flat work just fine on triggers like the blackburn. I'm darn sure Paul M had a reason for the notch. Maybe it had something to do with the notch in the side of the piece to allow you to recock with a shell case. (seems mightly slow to me)

Now the MKX speedlock version is another issue.

Any had any problems with mil-spec notched cocking pieces and Timney Triggers?

The "V" piece will lock up the bolt if used with a Sako trigger. After firing you will not be able to lift and move the bolt rearward. The Trigger sear will hang up in the CP notch.

Not sure if it was a Timney or Bold but one or the other or maybe both has locked up for me. Get a flat bottom and don't worry about it.

It is my understnading that the notch is there to allow the original style sear to rest in the up position when the rifle is stored uncocked.

It also allows the user to verify trigger/sear movement when the rifle is uncocked. I assume this might be more of a benefit in frozen or muddy military environments.

Never had an issue with timney sportsmans or featherweights with a standard cp.

Timney and Blackburn all worked fine on my mausers w/the std mil CP.

As far as the Sako hanging up, I have two on military sporters, a '35 Peruvian and a '36 Mex and never a lockup yet.

mark x triggers will lock it up, can't lift bolt handle.

There is a design difference if you compare the Timney Sportsman Trigger to the Timney Featherweight Trigger. The Sportsman is designed to allow the trigger sear to pop up into the v cut on military cocking piece and then to allow the cocking piece to ride over the trigger when cocking. The Sportsman can be used successfully on either the v notched or solid bottom cocking piece. The Timney Featherweight Trigger is designed to remain fully depressed under the cocking piece upon firing and therefore requires a solid bottom cocking piece. If the Featherweight trigger is used with the v shaped cocking piece it CAN on occasion pop up somewhat in the v recess and then cannot be depressed by the cocking piece as it attempts to ride over the trigger sear when cocking and therefor lockup the bolt. The Dayton/Taister can be used with either cocking piece as the spring design allows the entire trigger unit to move downward on cocking to allow the cocking piece to travel over the trigger sear. Trigger sear/cocking piece 101.
