What does SD weather have to do with anything? .................. Oh, wait, i get it, another deflection.



It is heat and burnt residue that wear breech plug flash hole. One thing that is true about this part of SD, there are tools available to measure things such as flash hole diameter.

Willingly or not, you will learn that flash holes erode. You will learn that breech plugs are not able to provide thousands of shots without showing wear. When you wrote that your plugs are good for thousands and thousands of shots, you were either wrong, or you...................................never mind.





Bye the bye, the weather in SD is usually quite good for shooting rifles.
