Hello,
As a newcomer to the wonderous art of "casting your own", I have run into a what appears to be a common problem with the .223.
I have been using a Lyman 225415 cast from WW with additional antimony and tin to increase BHN and castability. With Hornady GCs and lube they dress out about 55-56gn and are fired from an AR-15 with a 1in9 twist.
I have tried a couple of different loads using Unique and Red Dot with fair success (6-8gn). I've also tried some loads of IMR 4895 (18-21gn) but ran into the vaporising bullet issue. So far, I haven't had any issues with leading.
I understand that a heavier bullet with more bearing surface can withstand higher pressures and twist rates than a slender pointed bullet like the 225415.
I would like to try a heavier bullet, but am hesitant to spend the money for a new mould that may not work out.
Would anyone have any info on this or be willing to sell a few bullets (60-75gn) for testing?
I would appreciate any help.
William
