I use a few different things. I find they shoot identically, whether on paper, rested or standing or on gongs, all positions.
Spit - saturated patching
10% soluble oil/water
WWWF + a tich (6 ounces) of Neetsfoot oil - I used Blue Thunder -35 or -40 WinterWindshieldWasherFluid
A gallon of this will last a year or more depending on how much you shoot or what, $5.00 total?
This was used when we shot in freezing temps - all winter, but finding later in life, like now, don't like that much, any more.
The oil also helps slow evapouration in the hot weather (above 70F)when doing a trail of 30 or more shots with pre-lubed & precut patches.
