The second question I address frequently in regards to Muller Chokes is, "Why/how do your chokes stay so clean?" Here's why:
Staying Clean:Conventional 17-4ph stainless choke tubes and especially titanium choke tubes get dirty with carbon build up and plastic from wad buildup because they are malleable materials. The build-up is compounded by the fact that most choke tube manufacturers bore their tubes at an extremely fast feed rate in their turning centers, screw machines and CNC lathes. They do this to increase their production but the process results in a rougher surface finish than what is optimal. Carbon and plastic adhere easily to the rough surface and once they do, they continue to build onto themselves creating a filthy mess. This is why ported chokes such as Comp-N-Choke, Extreme Chokes, Briley, Kicks, Rhino and Pure Gold become dirty so easily. Muller Chokes uses a ceramic with teflon to create a surface that is like your non-stick frying pan. Not only is it harder than any other choke tube in the World at 60+ RC (Rockwell hardness "C" scale, competitors are usually around 40 or less) but it is very slick so nothing can adhere to it.
Most conventional chokes start to build carbon and plastic after only 50 rounds. Pretty soon, the build up causes pattern inconsistencies, point of impact variations and velocity deviation amongst other things. These are things that I could not tolerate and it is one of the reasons I created Muller Chokes. Every few hundred rounds, you may wipe the dust off of one of my chokes but you can say good-bye to scraping and brushing and spend your time shooting instead of cleaning your choke tubes.
Stay tuned for my next post which will answer the question, why do Muller Chokes produce consistently hard breaks at unbelievable distances?In the meantime, start practicing, warmer weather is around the corner!
