Of the several manuals I've checked I've found loads pretty well stop at the the 170 grain wieght. According to Speer's #13 manual they suggest that heavier jacketed big game bullets cannot be driven fast enough to expand reliably.
At 30-30 velocities 150 and 170 grain bullets have proved very reliable killers and make the most of the trajectory available from the 30-30.

These are some bullets that I have on hand . I am currently into lever guns and thinking about loading them for .30-30 .
They would be for shooting paper or steel rams . So expansion is not an issue & I doubt that hard cast lead would expand that much any way .
I came up with the same results you did in my reloading manuals .
But I will bet some one has done this ?
If worse comes to worse , I may load them in .30-60 . I found loading data for that .
Thanks ,
God bless

There is little or no data for 220 grain bullets in the 30-30 for several reasons. The majority of 30-30s in existence have a 1:12 rifling twist, which probably won't stabilize the longer bullet. Most 220 grain bullets, if they have the required cannelure for use in a tubular magazine, will have it positioned for the proper overall length of a 30-06, thus preventing feeding in the normal 30-30 rifle. Finally, many of the 30-30s have short throats and would have problems with a longer bullet such as a 220 gr.

The 220 grain bullet is a Krag bullet.Try it in a 30/40 rifle.

Wyr - Sam Fadala published some data for heavier bullets for the 30/30, but none that I remember over 190gr (he pulled from .303 Savage cases). I've tried his loads with cast and jacketed 180gr RN bullets with complete satisfaction. Velocities were just over 2000fps. I believe, as previously stated, that any bullet heavier takes up too much powder space. If velocity is reduced by much, trajectory will steepen. Considering that 220gr will stabilize in your slow twist rifle is another factor. You would probably have a better chance of stabilizing the heavier round by increased, not decreased velocity. (You usually have to drive heavier rounds faster in slow twist barrels, ie. micro groove 444 and slower in fast twist barrels.) .303 Savage user's touted how much more penetration their round would give with its 190gr jacketed bullet over 170gr 30/30 bullets and they didn't have much more powder capacity and used the same diameter bullet. I'd be interested what you come up with - good luck!

Shot the 220 grain bullet , yesterday in a 03A3 Springfield .
Initial results ( with 40 grains of surplus 4895 ) seems to be promising .
I do not have a .30-40 Kraig .
God bless

Had previously loaded some Lee 90371 185 grain RNLCG bullets .

Used 1.0 cc of WC820 surplus powder .
Went to the range yesterday . Results seem promising .
Another person gave me some data for the 220 grain bullet . I may try 20 grains of 4895 .
God bless
