What exactly is the purpose of a gas check?
A gas check does help seal the bore. How much it will reduce the dirt needs testing. 700X does produce more smoke for me, when compared to Bullseye powder. When the bullet jumps from the cylinder to barrel is when most happens. The gap between the barrel & cylinder, if on the large side may produce more dirt. Normal gap is .004" to .009"I am having issues with smoky loads from cast bullets in my 38 spl 642. They get the gun extremely nasty. It is a pain to clean and somewhat stains the finish. Would a gas check be a solution?
Nope. As far as gun cleaning goes, they're just the same as jacketed, with the exception of possible barrel/chamber fouling. (If you get a good bullet/load, barrel fouling is a non issue). Smoke can also be quite low in semiautos.Do the autos make as big of a mess?
