Installing a vent liner...

These are vent liners, Savage on the left, Lehigh on the right - I prefer the Lehigh, better metal and hardening process.



This is vent liners installed in a Omega plug



This is somewhat the process...



There also couple of schools of thoughts... One put the vent liner as close to the bottom of the primer as you can, and this is the one Western and other probably prefer, and the other one which works very well for me - is to install it out on the end of the plug. I prefer it out there as it increases the volume of gas the flash channel can hold. It can help reduce blow back pressure on the primer and the mess in the breech area, but to really control the mess in the breech - head space needs to be addressed.

Here are a couple of CVA plugs with vent liners installed.



One last picture that suggests what I think...
