I have been working on cast loads for my Marlin 336 .30/30. I recently recovered one of my gas-checked Lee 150 gr. bullets after going through several layers of wood, an old tire, and some corrugated plastic drain tile at 100 yds.
I was shooting a reduced load of 15.5 grains of IMR 4759 around 1600 fps.
What started out as a 150 grain bullet now weighs 148 grains, so it retained almost all of it's inital mass. The alloy was about 70% wheel-weight/30% linotype. Here is a picture of before and after. Expansion seemed to be pretty uniform, and the gas-check is still on. I was pretty pleased!
