You will also have to clear out the flash hole in the breech plug every 10 or so shots as well because the of the fouling that the 209 primer leaves. So I personaly have a ten shot rule.
Now I had just the opposite response with my Knight Vision and BH209. I ended up shooting about 26 shots during my last shooting period, using a Hornaday 350 gr FPB bullet, and never had to swipe my barrel once till after my last shot when cleaning.
I have also shot more then a dozen sabots during a period just before my last shoot of 26 rounds, with no swipes. This is one of the best things about this powder, IMHO of course!
I can only say you must be shooting a very tight barrel. I would ventreu to say you are shooting a T/C product. They are know for very tight barrels. Am I right?
