I've been experimenting with cast boolits in my Marlin 336 30-30. For a gallery load, 5.0 gr of Bullseye with a 311041 plain base (from a Lee 6 cavity Group Buy mold) shoots into one jagged hole at 25 yards. I haven't found a "hunting load" yet; I'm using Lyman 311041 cast from 50-50 WW and pure with 2% tin, weighs 178 gr lubed with Javelina (beeswax & Alox) and gaschecked. I read awhile back that you want to open the neck ID so that the case neck doesn't swage the boolit undersize when you load it. I FL size, then use the .311" expander ball from my 7.62 x 54R die set to open the neck. I then flare the neck with a Lee flaring tool. The 311041 casts .3095", I lube and seat the gascheck in a Lyman 450 with a .311" die. Am I on the right track here, or am I taking an extra needless step here? My goal is to launch this boolit at 1800-2000 fps and hopefully take a deer with it this season. Thanks for your input!
