So perhaps check if they will stabilise with your twist rate before bulk buying.
But I'm sure I'll be told to butt out.
I've used the Hornady 86gn ".30 Mauser" RN and the Speer 100gn "Plinker" RN in .30-30 and .30-06, and the 100gn XTP in 7.62x54R and .303, at subsonic and high velocities with accuracy no different to rifle bullets, at least at the close ranges they're likely to be used at (only the 7.62x54R has open sights, the rest have apertures, none are scoped). The very poor BC of these stumpy light bullets makes them less than optimal at longer ranges, they dump velocity very quickly and are significantly effected by wind. The BC of the 86gn is lower than a 40gn .22LR bullet, the 100gn XTP is a bit higher than .22LR. A subsonic load will have similar trajectory (around 200mm drop at 100m from a 50m zero), velocity loss, and wind drift as a subsonic .22LR bullet. Even launching it at 3300fps it's down below 2500fps by 100m, and below 1800fps at 200m.
I didn't find any deformation in the Plinker at subsonic velocities in wood or dirt though, they're very hard. I would use the XTP for live targets in subsonics, if it'll chamber in your rifle. The 110gn ".30 Carbine" FMJ bullet might also be a good choice if you file the nose flat to expose the soft lead.
