Do Pickett Brass backbores and mouthpieces affect my gap?

The diameter measurement of our backbores shanks and one piece shanks is 0.385".  Every mouthpiece receiver is different though - so we recommend checking the leadpipe/mouthpiece gap and adjusting to find the optimal gap for you.  

If you'd like to adjust your gap, you can request your backbore or one piece mouthpiece manufactured with a shank to accept Reeves sleeves.  Or we can custom make a shank with the diameter of your choice.
