I use mostly hollowpoints for practice. No real price difference, at least at retail.
Seems simpler to order one type of ammo rather than separate rounds for practice and enforcement. These aren’t SEALs or SFOD-D, they’re SSA Enforcement Agents. They’re only going through 600 rounds a year ... I doubt technical round selection is a major component of their job.
Seriously. Where are you buying your ammunition? What caliber? Are you referring to loaded ammunition, or reloading components?
Your claim is completely irreconcilable with my experience buying ammunition ...
But that's OK. If you can show where, for example Hornady XTP loaded ammunition can be had for no more than 10% premium over same weight, same velocity ball ammunition ...
I'm very interested to know.
