So I've decided that the next rifle I have built will be 7mm variant. I'm leaning 28 Nosler, 7mm STW, or a good ole 7mm mag. I'm open to any and all suggestions. It will be for both steel shooting out to 1000+ yards and hunting. I just want to hear any and all opinions of the pros and cons of any 7mm cartridges you guys like. Thanks in advance.
