Success! For those of you suffering from arthritis, 4.0gr of Titegroup under a 165gr hollow base bullet, when fired wearing Pearl Izumi gel-padded bicycling gloves seems to do the trick. My only complaint is that when shooting weak hand only, the bullets are going a bit to the right. Otherwise they all fit on a 7 in pie plate at 8 yards.
I can't use the Chroney indoors, so no MV numbers but I'm expecting something in the low to mid 800's.
