What is the general rule of thumb on hunting larger game like deer with cast bullets in the .277-.316 bullet diameter range, as far as bullet weight, sectional density, HP, no HP, and lead hardness.
For instance if I wanted to use a 270 Winchester fir hunting and used a cast bullet what would I want to use, how hard/not hard would I want to push the bullet,
trying to come up with some ideas on potential hunting loads for a few different calibers.
