.30-30 Win loads for 200g lead bullets?

Oregon Trail makes a 200g .309 GC bullet. I bought them to try in the .30-30 Win, but now cannot find load data anywhere. Even Oregon Trail has no recommended data for the .30-30 Win. I wanted to try these for our long range Cowboy matches out to 200 yards to see how the heavier bullet might perform.

Anybody seen any load data for these?

Thanks.

i would think the lyman book has some data. however getting a lyman book right now is about impossible.
try the ole 8-10 grs unique trick if all else fails.

The latest Lyman book only goes up to 173 grains, but the Second Lee book goes to 190. Shows:
Accurate 2700 29.7-33.0 grains
" 2520 25.6-28.5 grains
A-XMR 2015 22.5-25.9 grains

I don't use any of these, so don't know how these values will relate to other powders.

Hope this helps.
