I keep thinking that the 375 Ruger case necked to 7mm might be a great round. I would expect it to perform close to the Ultra, but with an OAL which is more magazine friendly. Would love to hear from someone who has or will be doing this!
i have a 7-300 weatherby that I am looking to sell. It is built on a sako l61 action and sits in a 2x2x9 bedding block. It will throw 175 smksa @ 3100 into a very small spot. E-mail me if you want to talk.
