Since nobody else has replied about being checked , the burden of proof is on them. best case scenario they make you shoot it over a chronograph to see the velocity, then use a KE calculator to get FPE. Our dnr discussed how they would deal with the issue if it came up and that is what their answer was. have your load data on your reloaded ammo box and be able to provide it to them. having the link to the KE calculator on your phone and being able to show them right there would go a long way if checked. .worst case, they seize your handgun and ammo for test firing. I think you would have to be in a real grey area to get to worst case status..
