If you think the powder is H4895 and work up a load using NEW H4895 and new components and it is shown to be safe in the load book how can you go wrong. Never once did the OP mention using the old powder, he was only looking at it to get and idea what powder was used in the old load. If he loads a new batch and it is a charge weight that is in a manual as safe how in the world has he done one thing wrong? A whole lot of "the sky is falling" advise was given out here.
