Hey guys,
I have a set of NEI blocks that cast a .430 bullet at about 335 grains, I think its a J D Jones designed bullet.
Its a plain based bullet, I would like to have a gas check on it. Would it be possible to machine it a bit deeper to add a GC? Does a bullet this heavy even need a GC? I shoot them in S&W 29's and my Super 14 Contender mostly but I have loaded them up in a .444 marlin at about 1500fps, I cast them pretty hard.
