While I don't own a single shot or bolt gun in 30-30, I do load various loadings of Spitzers through my old Winchester m94 30-30.  I used to load the above mentioned 150gr Ballistic Tip along with the less expensive and equally performing Sierra Boattail 150gr in the 2300-2400fps range.  I carried the lever gun with one in the chamber and one in the tube...kind of a two shooter if you will.  This is probably not a recommended practice but I did it for years anyhow.  
With such loadings I did see a noticable difference at 200 yards and beyond.  However, like GB mentioned, under that range, I could handle all shootings with ordinary 150fe FP factory loads or handloads.
For hogs, I don't have any advice as they are rare in Idaho.  I doubt I would hunt bear with a ballistic tip or the Sierra boatel or any boattail for that matter.  I just like putting two holes in game.
One day, I loaded some 180gr Ballistic Tips  in my 30-30 at around the 1700fps mark.  They handled themselves pretty well out around the 400 yard mark once I understood the trajectories which took a couple tracers.
Have fun.  My favorite 30-30 powders are H4895 and IMR 4320.
