I am pretty new to casting, but have been reloading for 15 years. I have a problem that is giving me some trouble with my 9mm loads.
I am using a Lee 6 cavity 125 grain tumble lube mold. Lubing with LLA / JPW / mineral spirits concoction of approximately %45 LLA, %45 JPW and %10 Mineral spirits.
The bullets hit at point of aim, pretty much, but the problem is that about one in five will be about 8 or 9 inches higher than the rest of the group, and a couple of inches to the left. The main group is more or less acceptable for the practicing that I am doing (3 inches at 25 yards) but I'm getting the darn flyers.
The bullets are dropping out at .358, the barrel slugged at .356 (Storm Lake barrel in a Glock 34)
I am using 4.5 grains of Unique for powder. The boolits are straight wheel weights.
I have had success reloading for years with commercially bought bullets, so I think the problem is with my casting.
Any ideas?
Dave.
