My stepkids like to go shooting with their dad. This is fine, doesn't bother me in the least. Only thing that kinda erks me is that they quantify how much fun they had in terms of how much money in ammo they shot up.
I, on the other hand, can take 50 rds of meticulously handloaded ammunition and spend the entire day at the range.
The fundamental difference can be summed up in the response to their mother asking, "So, what'd you shoot?"
The boy answers, "I shot my AR, and dad's AR, and his AK, and my Beretta, and a shotgun..."
Whereas my answer would be along the lines of, "Well, checked zero at 200, then hit some golf balls at 200, moved back to milk jugs at 4 and 5, then steel plates at 600 and 3 hits on the half-mile plate..."
Different strokes and all, but i generally feel like, if you're not trying to actually hit a specific target, then your money is better spent on fireworks than firearms.
