Thanks Randy for the reply
I have read several times on the net NOT to lube the sabots, but no one has said what the effects are, they just say don't do it. I won't do it anymore but I'd still like to know WHY!
The "why" is that it is unnecessary, and detrimental to accuracy.
Lubing a sabot will deposit the bulk of the bore butter (bore syrup in summer, bore rock in winter) near the muzzle of your bore. It cannot give you consistent bore condition throughout your barrel's length.
