Would need some way to soften it. Straight Track's mink oil is the stiffest patch lube I have used but then, only for hunting.
I did test the mink oil in my .32, using .320" balls and older 10 ounce denim that measured .0225" compressed. The 50th shot loaded
easier than the first in that test, no wiping at any time and short starter not actually needed, but makes 'things' easier and loading faster.
Those little balls load easily in tight combinations.
