I use my Inertia puller for 2 things:
Pulling apart stuff that my Hornady Cam Loc can't address, (Certain bullet profiles, soft lead, etc.)
Disassembly of small amounts of 'duds/mistakes' of different calibers.
(The cracked 45ACP case that you didn't catch until you seated it, the 9MM that was missing a primer, etc,)
My El-Cheapo FA puller seems to work well on 9, 38/357, and 45 ACP using the same set of jaws.
Takes too long to 'set up' the Cam Loc for just a couple rounds in one caliber, switch collets, 3 more in another caliber, switch again
For 'Quantity' and profiles that the Cam Loc works on, no contest. Cam Loc* wins.
