Hello everyone. I'm wanting to start loading 7mm rem mag and I was told this is were I need to ask. I have a remington 7mm that I have been shooting 150gr factory loads out of and now I have a bunch of brass accumulated. What brand/type of powder works best with 7rem mag? I have considered the Hornady 162gr A-max for a bullet but am not sure if I need to use 140gr instead. I didn't know if any one had an opinion on the subject about what has worked best for them of what conponets I need to buy. Any and all help for this newbee would be appreciated
