Not sure that makes sense.
Guess I gotta agree with you... I shoot T7 and BH with Montana Extreme in the barrel - makes no difference for me. And like you I do run a clean dry patch before shooting and I pop a couple primers - load up and I am off to the races...
The only thing it cold really effect is the sabot might slip/skip the lands if it were over oiled. If you are shooting BH you need to use a fairly tight sabot anyway and if you pre-foul with primers - you should not slip or skip.
I certainly have not shot as much BH as some but I really can not say it is more accurate for me than T7.
Where BH is the best is when you are shooting heavy bullets... BH is far more effeicient with a heavier bullet. When I tested a 200 grain bullet from this new Triumph I actually got greater velocity with the T7-2f than I did with an equal load of BH...
