Used to be the only rifles allowed in Indiana, PCR.
The .44 mag Marlins and H&R popular.
Private ground reg HP rifles also became legal.
Think entry level .243/.308 stuff like Axis/RAR top sellers.

When PCR only I ran a Ruger .44 auto sporter or a TC Contender in .35 rem (trimmed to meet spec).
Since reg HP rifle has been legal (test period) I've run a Ruger #1 RSI in .243 win and a Rem 760 in .35 rem.
Bought a Steyr Prohunter for crappy weather, in boring ol' .30-06
