When Ihad my 30-30 Handi, I did a bunch of shooting using pointy bullets. They shot very nicely, and I had no trouble getting reliable expansion with any of them including the Nosler 180 Partition which I was driving at 2250 fps (I wouldn't do that in a '94 or a 336 for that matter)
The bullets I used were:
Sierra GameKing 150 SPBT 2360 fps
Sierra ProHunter 150 SP 2360 fps
Hornady SST 150 2390 fps
Nosler 150 Ballistic Tip 2340 fps
Nosler 180 Partition 2260 fps
Sam Fadala was did a good bit of research using 180 grain pointy bullets in the 30-30 in an effort to get 303 Savage performance (190 grain bullet at 1950 fps) He had really good things to say about the Speer 180 Mag Tip and considered it a fine substitute for the 190 Winchester Silvertip bullet of the 303 Savage. As has been emntioned, in a 94 or 336 you'll ahve cycling problems as teh OAL is too long for functioning in the leveractions, but they can be singly loaded with very good effect. All the ballistic programs I ran on these bullets/loads showed trajectories being about 3" high at 100 to be 2.5" or so low at 200. The Partition didn't fair so well showing only a point blank range of 180 yards for a 5" circle.
It is a worthy endeavor, susbstitute pointy bullets weight for weight and always begin with starting loads and work up. If Ihad to choose one of these loads for a 30-30 I'd be torn between the Hornady 150 SST and the 180 Partition.
