That is typically a magnum powder. However, high volume small diameter cases can use it, i.e. .243 and 6mm Rem. It's only going to really work in those cases with heavy bullets. With a tight twisted 6mm barrel pushing 100+ gr. high BC bullets it will work.So I have several ponds of h1000, do any of the previously discussed cartridges work well with it?
.257 Roberts and 25-06 will benefit only in the 117-120 class bullets.
