I did get out Sunday to run another test on the new Gen II plug. This time I took the Extreme MHC 50 cal out for the test run run the new plug.
My goal again was to observe cleanliness and the ability to shoot BH consistently with a variety of primers....
It is my belief the the Lehigh Vent Liner is one of the single most biggest advances to a breech plug in years.... Not just because it can be replaced at some some point in the future without buying a whole new breech plug, but the abilty that it give you ignite powders with a variety of primers.
Western Powders and Lehigh continue to suggest that you should use a hot primer to ignite BH, either a Federal 209A or a CCI-209M. It is my belief you can use most any primer you want to ignite BH if you have the vent liner in the BP.
OK - I should say that I am not saying that other BP's will not work with different primers but i think the vent liner adds reliabilty and extended use...
Sunday i shot 15 shots of 110 grains of BH with different primers and got instant ignition with all. Also comparable velocities and and comparable accuracy, especially for me shooting through a chronograph as I spend more time focused on it than I do the target. The other factor was I was on a time limit so I was shooting one shot right after another.
Cleanliness.... the Lehigh BP was installed in the gun with the longest measured breech area, so i was concerned the primer(s) might leak a little blow back as not all primers used toched the primer shelf in the primer pocket.
I really was not dissappointed... It was great. There was a minimal amount of blow back dust - but everything just wipped off. I really believe I could have continued to shoot the rest of the day without cleaning or disassembly of anything. Not only that the 'flash channel' showed very little sign of 'clogging up'. I do not think it would have...
Here is a set of pictures after the shooting trip...
In two of the other DISC's I have I would have had a tighter fit and even less dusting....
Here is the target with the different velocities for all 15 shots with the different primers... Hot ones and cold ones.....
All loads were volume loads thrown at the shooting site....
Do not get to critical of the grouping - i was in a hurry and i know I had a couple of OOPs!!! along the way...
All-in-all I think Lehigh Dave has a winner product....
