The 220 / 219 have a very stout coil spring behind the ejector.
Drive the cross pin out of the bbl lug that holds the Ejector in place.
The ejector will pop free and the coil spring behind it.
Replace that spring with one of similar diameter but lighter compression weight and you won't have the hulls blasting off for the unkn.

The 219 version in .22Hornet throws those little weight nothing brass cases into orbit if you're not watching.
