Was shooting my 105 year old ITHACA FLUES 12 ga. with Browning ''little Skeeters'' inserts for 20 ga. shells tjis week.
couple folks told me when I bought them about 6-7 years ago that I just wasted my cash.... Well,they have worked flawlessly. I have no trouble shooting 12 ga.field loads in the old gun.....but shooting the 20 is a pleasure....very little recoil and the 20 patterns well with 7/8 or 1 ounce federal target and field loads...
sort of like an overbore barrel.... wad SEAL the shot charge upon firing and the load is NOT appreciated by local blue and ruff grouse.
certainly a lot cheaper than buying a double 20 these days.
