I don't think so... although the "bombs" don't contain explosives.
"Annually, approximately 1,000 sorties from fighter and helicopter users throughout the northeastern United States practice weapons delivery day and night at the range. Typical users seen at the range include the A-10 Thunderbolt II, F-16C/D Fighting Falcon, and F/A-18 Hornet fighters, AH-1 Super Cobra, UH-1 Venom, CH-53 Super Stallion, and HH-60G Pave Hawk helicopters, as well as C-130 Hercules and C-17 Globemaster III cargo aircraft."

If you export your waypoints from Mapsource in .gpx format (as opposed to Garmin's proprietary .gdb) they should be usable across a wide spectrum of devices and software, it's a universal format. But I got off the Garmin train a few stops back and have no personal experience with their new devices. It would be hard to imagine they don't support .gpx files however.
You can also import your .gpx files into the boydsmaps app on your phone and/or computer. Just press the flag (waypoint) button to get started.
I saw no one on the bombing range that day, nor do i recall ever seeing military aircraft over those places in the old days, but maybe i just don't remember them.
All my waypoints are saved in Garmin's .gdb format. Is there a way to change them en masse to .gpx?
