Greetings all. I'll be acquiring a SU-22 shortly and was wondering if it cycled subsonic ammo after break-in (or before) OK. What brands are you using? Most of my rimfire shooting is done suppressed and I typically use CCI subsonic or standard velocity. The CCI subsonic HP has a large driving band & is hard to chamber in some guns. I've read that the SU-22 has a Bentz style chamber for accuracy and was wondering what kind of ammo ya'll are using. TIA.
