[QUOTE="J E Custom, post: 1791348, member: 2736"] In my opinion, N 570 is a very good powder for the really big magnums. it is one of the slower burning powders and gives good velocities. It is also a little over priced in my opinion, but for the performance I will pay a little more. As far as heat sensitivity, I have not seen it in this powder but I hold max pressures to 62,000 Psi and these characteristics show up more often when you load on the top end of the recommended pressures. Here in south Texas, we often have temperatures of 100o+ and if we load hard, many powders will appear to be somewhat heat sensitive. The chronograph is a better tool for finding out the heat sensitivity at Lower pressures because the velocities will spike suddenly when heat sensitive powder are used at elevated temperatures. It is always best to work up with any powder and keep good records on velocity and temperatures for each load. J E CUSTOM [/QUOTE]
