What about after they release another batch, when it's gone wait another year before anymore is available.
I just dont trust company's to just say when something will hit the market, look at the berger bullet 156 and 245.
I personally am not gonna buy 8lb jug of a powder to try just because somebody says it works for xyz, every gun and barrel is different. When its proven for me then I buy enough to last that gun or barrel.
I dont doudt 570 works well but until I'm confident theres a better supply I will shy away.
