Atn xsight 4k pro

I also have the 4K pro and ABL 1000. I have found the G1 or GL drag profiles work best. I highly recommend purchasing Strelok pro and comparing the ballistic calculator on the 4K to what Strelok says. I increase the FPS in the 4K profile to get to what adjustments Strelok says needs to be done. Slightly modifying the BC in the 4K profile will also fine tune the scope to get the Strelok numbers.

Yes it's a lot of messing around to fine tune the 4K ballistic calculator, but well worth it in the end and it gets easier and faster once you're used to it. I love being able to switch between different pellets/slugs on my Impact M3 in a matter of minutes and being dead on.
