With a 243 a guy could neck up pretty easy, or a 308 you could neck down. With all the talk about kid/women friendly cartridges I don't know why no one has done this. Is there a reason that there isn't any real 308 parent case necked to 277? I mean we've got it bracketed on both sides with the 243, & 7-08. Then we've got the 308, & 338 Fed, so why no 270 wildcat? Seems to me like it'd be the one to benefit as far as case volume, & bullet wt goes. Anybody got any idea? I'm kinda brainstorming for a build. Now, Im a very opinionated person, so Don't take it personally, but I'm not a fan of any 6.5, or 7mm in any configuration so that's out. The 338Fed just seem like a ballistic nightmare. And the 308Win frankly bores me to death. So, that leaves me with the 243. Ok, i know it'll do the job, but so will the others I've already mentioned. It just doesn't strike me as anything but a big coyote gun. Ya ya I know a ton of ladies who've killed Elk with them too (not impressed). Please understand I'm not "bashing" anyone's favorite cartridges here. I'm also fully aware of the ballistic advantages of the 6.5, & 7mm's on paper. I don't need a tutorial on it. I just want something different, for my wife & daughter. I'm a Huge 270, 30, & 338 fan in most configurations. They perform well on the critters we hunt in "out west". Plain & simple. But, For me, the 308Win case capacity alone rules out the 30, & 338 as ballistic dog turds, and the 243 (to me) is simply a cross over gun from varmint to thin skinned game. I've got an old Model-70 in 243 that'd be a great platform for a build, so Why not a 270-08?
