Anyone else having trouble with these? Yesterday while sighting in my TC Hawkin with a Green Mountain barrel, I found a great difference in the seating of the mini balls they sell. Some would load with just some initial resistance, then flow smoothly and others out of the same box literally stuck in my barrel forcing me to pound the ram rod with a hammer to seat. I tried running a solvent patch and then a dry patch after each shot but still had the same problem. Not suprising the ones I had to pound down went who knows where.
