McLernon.
There is no question that a bedding system like yours or mine will improve accuray, specially for us Canadians we can't get any switch barrels.
I have detailed instruction in the FAQ how to accurize a Handi, but sofar I have heard from nobody that has done so.
The reason of course is the switch barrel syndrom, which prevents the action bedding from working.
My two Handi rifles are both fully bedded and both shoot 1/2" 3 shot groups, also they both are rebored and rechambered from 223.
