New to reloading for rifle rounds. I am trying to start reloading 7 Mag and have H 100 V for powder, Mag match primers and need some advice on bullets. Bought 140gr Nosler Ballistic tips and looking at the Barnes 140 TTSX. Has anyone used either of these bullets ?? Also looking to reload an 8mm Mauser, what powder will be the best for my Mauser ?? Planning on rebarreling the Mauser with a 26 inch barrel among other things.
