We are looking at building target rifles to sharpen our shooting skills. I currently shoot a 6.5x284 and she shoots a Tika 3006for hunting. Want to build target specific rifles .We have a 600 yard range close to home when we retire next year would like to do some travel to places with longer ranges .Fairly new to reloading but plan on doing for this. Would like some suggestions on what you would build if you could for 600 and beyond. Ideally we would shoot the same caliber. So let's see what you would build.
