is there any reason to use magnum. im dont really understand what it does thats special. try to explain please. what bullets would u guys recommend for a load that could be used to take deer bear and maybe boar or elk sometime. mainly deer though. any bullet recommendations are welcolmed and wanted. what would u think of a 165 partition. thanks
Generally, for the larger/magnum cartridges the magnum primers are used to provide
a hotter spark for use with the slower burning powders. There's something to be said too for more uniform ignition & complete burning of the powders in the larger cases. But, it all comes down to what works best for your rifle. It's not unusual to find a load that shoots best with standard primers, and not the magnums. Temperatures can play a part too. If hunting in extreme cold climate a magnum primer could be advantageous.
Now, for the game you noted I'd be inclined to try a good 165gr. bullet such as Nosler Partitions, or Trophy Bondeds. Maybe the newer Remington Core-Lokt Ultras.
If however, you're looking a LARGE bears (griz & browns), then get some good 180gr.
