I always try TWO lubes because I have not found rhyme nor reason to foretell which barrels will prefer which lube.
And the process starts with the pellet that already shoots best in that barrel at that speed.
a) Baked Pledge.- You take a tin of pellets and split it between three paper clips metallic mesh desk holders. Two short squirts into the holders without spraying the pellets themselves. Swish them around about 50 times.
Bake in a toaster oven at around 270 °F for three minutes
Let cool.
If you did your job well, you will find that the pellets are mildly sticking to each other, swish them around again a few times to separate them and put them back into the tin
b) T-9.- Get a strip of lint-free cloth, about 6" wide and 14" long
Put a "line" of the lubricant across the middle of the cloth, perpendicular to the long direction
Place the pellets on one side of the lube line and by raising alternately the right and left sides, make the pellets cross the line a lot of times You will need to "gather the ends" to prevent spilling pellets all over.
Once you are done "hammocking them", return to the tun to dry.
One of these methods will show a marked improvement "from the get go".
From there on, it is mostly a matter of tuning the harmonics to the pellet's traverse time.
HTH, keep well and shoot straight!
