I cast my first bullet in 2007 and lubed it with Darrs lube. By 2008 I was regularly shooting about 1" per 10 yd off hand Weaver stance with the 6" 357 Sec6 and 7.5" RBH 45 Colts . With full tilt loads , 1200 fps 158s and 1050 fps 255s and a little Marlin carbine in 357 that would run 1550 + .
Some may remember my difficulties with an 06' that had 4" with both ends clean and a generous lube star with 11" of lead from doom in the middle . Short version the rifle had a lifetime of super heavyweight jackets and the bbl was swollen where the powder charge really came to life . No big deal now ,then dispare and depression . A few lapping rounds and that problem was solved. The chamber will take .314 but it's .309 when it leaves the muzzle .
Anyway Darrs lube 18 paraffin, 14 Vaseline, 3 tbsp STP rather that the 16/16/2. Oz plz.
Fast forward same lube end of the batch actually still kills hogs dead out of an unleaded 20" Colts carbine pushing 1425 and it works fine in 2400 fps 27&28 cal and over 2500 in 222/223 . I suppose I should try something else but 5 hogs and a mulie with jacketed velocities in some cases with 1.5" groups is pretty to hard to argue a need to change things especially in rifles that offer 2+" groups with factory ammo.
"KISS" , big sign over the benches .
