I'd recommend SS pistol loads also. I've gotten great accuracy with the 130 gr Hornady spire (#3020) and the 125 gr Ballistic Tip using IMR's max load for 3031 for the T/C Contender. The abrupt ogive of the Hornady bullet won't allow you to use IMRs COAL, but I seated mine just deep enough that the action will close and have not had any problems with pressure signs.
Good luck with the 748, my Handi doesn't like it nearly as much as the old standby stick 3031.
I also tested some 150 gr Speer BTSP, tested for velocity but not accuracy. The Speer boattails are of slightly lighter construction than their spitzers, and I think they'd work well at 2400-2450 fps. The Mag Tips also look interesting, but I haven't tried them. Speer advised me not to use the 165 BTs at .30-30 speeds, suggested their 130 FP for single shot .30-30s.
