With no disrespect to you, the rings are intentionally bigger than the bore when relaxed. That is so that they “ride” on the cylinder walls to give the compression needed to keep the engine running.

My experience is that if I work the ring too much trying to remove it…they break…. makes me say bad words, but then it is always my fault they break.

Put the ring in the bore, by itself, use the bottom of the piston skirt to ensure it is true in the bore, measure your end gap to proper specs, if it is the range, reinstall it on the piston an go.

Took your idea and that worked. Thanks
