It seems that the plastic from the sabot would fill the rifling in the barrell, therefore making them less effective on the bullet. And then wouldn't that make the barrell harder to clean?
I guess the first thing I would suggest to you is that the sabots is not made of just plastic.. It is an advanced polymer formulation, that is also providesself lubrication as it travels up the barrel. How tightthe sabot/bullet combination is in the barrel has a lot to do with velocity and accuracy of the projectile. Also the the sabot and projectile (except maybe for a all copper Barnes will obturate to the diameter of the barrel is the gas seal remains tight. Manufacturers of the sabots will tell you oil in the barrel is not necessary (and it isn't)- because the last thing they want is the sabot slipping up the barrel and not engaging the lands... I have tried testing both this thought and my belief because I do have a
very light coat of bore protection in the bore while I am hunting. In the weather I hunt in damp, rainy, snowy - I just feel better if the bore is protected from moisture - anyway I get no change in accuracy from a stripped clean metal bore and a very ligthly protected bore.
Just another thought from the peanut gallery....
+!, I have also found that I can use synthic oil with BH209 and by wipeing it well before loading put that first load in the group. Lee
