RE: 777 Powder
River Rat,
Don't sell the 100gr load with the 250SST short. I use the 250 Shockwave (same bullet) over 100gr of 777 in a couple of my rifles including my son's Apex and get good accuracy out of it. I have gotten several sub 4" and a couple of sub 3" groups at 200 yards with it and would not hesitate a 200 yard shot on a deer that's broadside. Here is a chart for that load in the Apex.
Name: .45 Cal, TC Shockwave, 250 grn
Ballistic Coeff: 0.210
Bullet Weight: 250
Velocity: 1780
Target Distance: 135
Scope Height: 1.500
Temperature: 70
Altitude: 500

The energy is still above 800fp at 200 yards and the drop is reasonable and easily adjusted for. This chart is set up for a 5" point blank range which gives you point and shoot to a little over 150 yards. Give it a try.
