Gnoahh's idea of the cast bullet looks good as well. I've already got that mold. I will probably give it a try. After the Obama years, I'm always on the lookout for a DIY alternative.
I doubt you have that mould.
I designed it and had Saeco make it as a custom job back in the 80's. The body length of the bullet is designed to fit neatly in the neck of the .30-30 without protruding into the powder space, and the ogive above the crimp groove is designed to fit the ball seat (throat) of typical .30-30 factory chambers, with a nose diameter of .301" to give firm support on top of the lands for a bore-riding effect. Body diameter is .310 as-cast which has given good results in many .30 rifles when custom sized to throat diameters. (Ignore groove diameter- throat diameter is key.)
