I received my FX Ballistics Chronograph on Saturday and finally got a chance to shoot over it a little bit Monday afternoon. I am in the middle of testing some 40g Slugs to swap to over my 34g slugs. And have an easy tune to swap between as well. The first picture is my 34g and the other 3 are my 3 different 40g slugs. This radar is amazing!!! All I have done at this point in testing is shoot with my 34g tune. The groups are just outside 1" at 50y for the 40s. My 34s are right at 1/2" at 50y. More to come as I get more testing with this radar system.
