I need to confirm my data from February, but if it holds up I'm looking at around 38.1 MOA (or about 114 inches) of drop to dial in. I know my cheapo Barska Tactical has at least 30 MOA available but I have to check if it has 38.

Energy looks to be around 620 ft-lbs. Given that I cleanly took a doe at 338 yards with 500 fl-lbs of energy (pass-thru on both shoulders), that's pretty impressive energy that far out. This is just target shooting at this point though, not preparation to shoot a deer that far out. I'd want to shoot into some media to test expansion before I did that, I know a 200SW performs well at low velocity but I do not have the experience with the FTX to trust it yet.

Drop is the easy part, shoot at 100yds and 300yds, run the calculations and verify at 400, then move to 500 yards. Wind is the real issue with long range shooting, a 10mph crosswind would generate about SIX FEET of drift at 500 yards. I won't be attempting it with much crosswind, my target backer will not be huge.
