I have the hydralic lifter for 12 gauge as well and like it's results very much. When I priced them for 16 and 20 gauge recently and found them close to $500 each I looked for cheaper alternatives. I was advised from this Board to use "GAUGE PINS". I purchase two (2) sets to cover all gauges from 28-12 for about $125 total from Ebay. These work just as well if not better than the lifter at much less $$. If interested SKB from this site can advise on their use.
