Hi everyone. I'm currently developing a load for my 458 lott using the Barnes TSX in 350gr. Since I live in Sweden the powder that I will find most frequently is Normas powders. But I don't really know where to start. Today I did some loading using Normas 200 powder. Start weight is 75gr and so far I have loaded up to 77gr. I have tested them yet but is these load to hot or do you guys think I'm on the right path? I was looking in Normas reloading manual on other 350gr bullets for 458 win mag and used the max load for a start load.
