Most every sabot manufacturer and barrel manufacturer recommends a dry clean barrel for accuracy, sabots are self lubricating. But, there are lot of people out there that are still using Natural lube 1000 as a patch lubricant to swab the bore between shots or are applying Bore Butter to the sabots to aid it in its decent down the barrel. As you know, I feel, if you are shooting a 50 cal. with a .451/.452 bullet you can find a sabot that will work in your gund with out lubricating the sabot to get it down. If you buy pachages of bullet/sabot combinations and are unwilling/unable to switch sabots you may be destined to lube the sabot to get it down.
I really do not recommend (which is worth about 2 cents in the real world)the use of the natural lubricants while shooting. I
do use BB in my barrel care process, in a strip clean,which Ibelieve may aid loading and certainly reduces fouling for a given amount of time. While hunting I do not hunt with a bare metal barrel either. I usually shoot the gun preseason to check POI wipe clean the barrel, certainly not a strip clean, then I do put a verrry light coatof a quality bore oil in the barrel and then wipe as much out as can get with a clean dry patch. During the season any shots thatI might takeI follow up with the same procedure, but any time I am in the woods hunting there is a light coat of protective oil in the barrel. This has not had a noticibleeffecton my POI while hunting.
In a recent conversation with Del Ramsey, I shared with him my concern (question) about sabots slipping by or across the lands and grooves. I was especially concerned, not because I have a light coat of oil in the barrel but when loading some sabots they slip down almost like a PowerBelt. I was sure this would lead to sabot slippage across the rifllings. He indicated, in his experiance he had not been able to create this problem with a sabot of the correct caliber and the correct bullet size. He indicated when the projectileis fired a lead bullet will "obturate" and create an "interference fit" with the sabot and riflings in the bore. The only time that this slippage might occur is with all copper bullets that do not obturate.
