Looking at choices for hollow points for SD (specifically 9mm). Seems like the cost is about $30 for 25 rounds in town: Golden saber, PDX1, Gold Dot, etc... Now Ranger is about $30 for 50 rounds in town. Listening to my police friends recommendations, being a bit value minded, and at the same time wanting to do more practice with the same ammo that I carry I have gone to Ranger ammo. Can someone provide a good reason why Ranger is about 1/2 the cost of other rounds? Volume of rounds produced? Old design?
