My TC Omega used to be very finicky. If I changed the sabot or gains of powder by 5gr I'd get a fairly significant deviation in POI. Since I am getting low on Deep Curls and my scope's windage and elevation adjustments SUCK, I wanted to see where other loads for bullets I had on hand would impact at 100 yards.

300gr Deep Curl HP, Harvester Short Black Sabot, 110gr BH209: Bullseye (zeroed for this load)
270gr Deep Curl SP, Harvester Crush Rib Green, 110gr BH209: Bullseye (slightly low and left)
250gr Barnes SpitFire T-EZ, Harvester Crush Rib Black, 110gr BH209: Low 1", Left 1"
250gr Scorpion PT Gold, Harvester Crush Rib Black, 90gr BH209: Low 1", Left 2"

I really don't know what happened to my gun but I can't complain! It very rare I will shoot at game past 100 yards…most shots are within 40.

What kind of variations do you typically see with your guns?
