I have a question,I shoot hornady 300gr hp sabots and bullets out of my great plains hunter flintlock.They shoot incredibly accurate ,only drop 3 1/2 inches at 100 yrds.I'm very happy,but I was told that the plastic from the sabots will build up on my riflings ,causing problems.Is this true? and if so how do I clean it out ? What do I clean it out with? And how often will this build up and need to be cleaned? or is this false and doesn't build up at all? I'm asking you inline guys because you guys shoot sabots out of inline M/Ls.Any advice or info would be appreciated!
