I don't remember why right now, but I have like 12-13oz left of LilGun, so over the last 2 weeks I have been reading about using it, and researched on QuickLoad V3.8 as well.

I am waiting for bullets sized at .432" to arrive, so I have been wanting to use these old 240grs, which are unfortunately sized to .430" (my bore has been fired lap, so it starts at .432"-.431" and by the time it exits the muzzle is about .4302"-.4305", so these are definitely too small. But, I felt like trying them out anyway while I wait for the other ones :)

Using QuickLoad, I decided to to try traditional steps, so I loaded 19.5gr, 20gr, 21gr, 22gr, and 23gr. I am using R-P brass prepped at 1.275", WLP, and the OAL=1.601":

I have not used my Chrony in a while, so the first string was a mix of a different slower lot, and these LilGun loads, so the data for the first string at 19.5gr has no SD, but every other one is complete:
(load in gr of Lil'Gun, low, high, average, spread, SD) - all strings were 5x shoots except the last one
19.5gr, 1178, 1214, 1200, 36, ???
20.0gr, 1200, 1288, 1229, 88.13, 35.66, 19
21.0gr, 1237, 1285, 1257, 47.73, 21.58, 24
22.0gr, 1233, 1324, 1278, 86.99, 31.98, 29
23.0gr, 1299, 1343, 1328, 43.86, 25.11, 32 (only 3x shots)
My eyes are not as good as before, so I can't give you valuable data on accuracy, but based on these, I am inclined to try the 19.5gr range some more. Note that QuickLoad V3.8 predicted 1047 fps and 81% load density with the 19.5gr load.
