I only used 3 primers yesterday... Winchester T7, Federal 209a's, and Remington 209-4's. I will use others as I get to do more shooting, which I was suppose to do today - but the weather has gone bad.
You might be interested in this observation of mine... Even though Western and even Lehigh says to use the Fed 209a or the CCI209m with black horn... I have continually ignited, instantly ignited, 120 grain loads of BH, with any primer I have used. It is my belief that the Lehigh vent liner makes that possible.
In your testing, what particular primer functioned (i.e. inserted and extracted) and in general was the best fit with your Lehigh plug ?
Let me do a little more testing before I declare that...
One thing to remember the primer pocket is 0.195" deep.... and in some Knight Extremes/Elites that is going to be a tight fit with Winchester primers a good fit with the Federals and a looser fit with the shorter primers. And then again with other Knight's it could be just the opposite.
