Hi all. Im new to this forum and to long and medium range shooting. Wanting to take my first step into medium 400-600 yrd shooting. I have several guns and calibers in mind.. I currently own a Savage 116 fss in 270 Winchester 23in fluted barrel with factory muzzle brake and a FNAR in 308 with 20 in barrel.. I am presently entertaining 2 rifles and 2 different calibers. First is a Savage: Savage Arms Second is a Remington Sendero SF II CALIBER choices are either 7mm win mag or 300win mag. If I go with the savage it will more than likely be a 300wsm due to the fact that the Bell Carson stock I would buy for the Savage only comes in short action only.. I do intend to reload.. I use the 270 for all my hunting so I am looking to build something to punch paper but still give me something to stop BIG Aliens and zombies.. Any help is appreciated!!
