Can you tell me what method you use to prep the breech plug when installing a new knight-Lehigh plug (tape or grease) when your shooting T7 and BH209.

Tape for both will be just fine. At least it has been for me.

Works for me too.

Both work . Tape is less messy. Stretch one layer of tape tight its what works best for most of us.

I use just a bit of BP grease on the vent liner - if you have a vent liner that you can remove, which it sounds like you will not. I than tape the BP. I use the pink tape in most Knights but in two of mine I have to use the thinner white tape.

I am a worry wort. I use tape and then just a very thin film of anti seize over the tape. The reason I do this is I have had bad experiences with just tape. Not that they don't come out, but to get them started they seem to take a little more pressure on the rifle then I like to give. So with just a light smear of the anti seize also, they back right out.

Both will work fine for you. And I am sure the tape is a lot less mess.

I use tape too and just a very very light amount of MX oil on both threads. I like anti seize better but i hate cleaning up the mess it leaves.

Thank you for the Information ,I will give the tape a try.
