Are you aware of the different breech plug conversions? There are several out there that you switch the regular breech plug to a breech plug that you insert a shell casing into.

The 25 acp conversion is one of those conversions - several people have indicated that they an excellent conversion. I have a 32 H&R Magnum conversion for my Austin and Halleck.

Depending on which rifle you are using there may be a conversion for you.

If you are shooting pellets, especially T7 pellets one of these conversions might be what you want. The conversion does clean up the breech area also, they seem to reduce blowback significantly.

I still prefer the 209 breech plug at this time, but I am shooting t7 loose powder.

I hope I provided you with some information that might be pertinent to your question.
