Test #1 of the new Lehigh Generation II Knight Breech Plug.
Been gone this past week to Missoula for some training, when I got back today I had a package with a NEW Lehigh Generation II breech plug in it.
The new plug is suppose to help in a couple of areas. It should provide a better primer pocket depth to reduce blow back from the primer area. It should also provide a better 'headspace' fit to the bolt face.
I could not resist the urge to try the new plug this morning in a 'primer cycling' test. I installed the plug in what i call my tightest fitting gun and in the loosest (not a word I know - but you know what i mean...)
From there I cycled 9 different 209 primers through both rifles. I cycled the longest primers I have the Winchesters, 2 types, and the shortest primer the Remington 209-4. I also cycled the CCI 209's both the 'M' and the regular primer. These primers are a bit fatter than than the others... The M's fit and pulled out just fine, the regular CCI 209 were snug going in and did require a small tug to get then out but they came out easily enough. I am confident a little use of the BP will polish and smooth the primer pocket to the point that the CCI-209 regular primers will work just fine.
Remember everyone, these plugs are machined to fit a true Knight DISC Elite or Extreme. If you try to use them in others in the model line, they may not fit as well. I have found Knight has some very wide tolerances in their manufacturing process. Now on the other hand it is my belief that they will work in may of these other Knights but you will not know for sure until you try.
Here is a pic of this mornings efforts....
Hope to shoot both this afternoon and tomarrow....
