I'm looking for a bullet I can powder coat and which will 100% function in a ar15 300blk. I have been using a gas checked Lee 312-155 -2r which works about 95% of the time. when it does not chamber the nose is always the issue because it is to large. A great bonus would be if it also happens to work in the k31, the short throat in the k31 has defeated all of my attempts to shoot cast.
If you have a few samples of the suggested bullet I would be glad to purchase some to test.
