JBear;
I've got two 30-cal flavored barrels. 30-30 and '06. The 30-30 has Marlin-like 'micro-groove'-ish rifling. The '06 has traditional, wider lands & grooves. They were both fitted by Brian56 last year.
I take a reduced load approach for my '06 loads and usually make 'em shoot like a 30-40 Krag. The folks at Hornady list their 30-30 170gr RN to go no more than 2300fps. With 40gr of H4895, it chronos right there. Easy on the shoulder; barrel & receiver. (not that the Handi can't handle full-up loads). Should work great as a 'woods' load, although I used the 30-30 barrel for deer this year. I switch to a bullet with a longer ogive for my P17, usually a Speer, as it doesn't like the RN out of the box magazine.
Good luck with the '06. There are TONS of recipes out there (be careful of course), stick with verifiable sources. You'll find bunches of 'pet' loads.
