Why would you waste hollow point rounds at a gun range? They are way more expensive than non-hollow point.
You should always periodically check the operation of your piece with the ammunition you’re going to use to fight with. There are possible differences between it and ball ammunition including failures to feed, eject, and changes in point of impact between the two types (admittedly this last tends to be negligible at most self-defense ranges but it’s still good do know). And you’re right, it ain’t cheap.
I guess just to make sure they feed through your gun okay.
