How was your New Knight Mountaineer .45/1:20 Twist Barrel assembly for Headspacing?
The Lehigh Plug is a MUST, VERY High Quality Breech Plug, The Plug itself Should Last the Life of the Rifle If Properly Cared for. The Lehigh Vent Liners seem to LAST N LAST Which is AWESOME! After all of the Shooting i did with my Mountaineer, BIG HEAVY Lead, and Reasonably Stout Charges of Swiss Real Blackpowder (Recipe For Eroding Flash Channels) My Vent Liner flash channel showed ZERO wear, it was Literally like Brand New the Last time i Shot it. I can’t speak Highly enough of the Lehigh Plug, and Their Vent Liners, They are TOP SHELF!! When Properly Headspaced in a Knight Mountaineer, Or an Ultra Light, As Good as it gets in my Opinion for Factory, Current Production inline Rifles
Headspacing these Plugs is NOT a Big Deal, in fact it is Extremely Simple to do, Hopefully Threads like this Help educate Folks on Doing it, the importance of it, and how easy it actually is to do.
