Mike at Ammoguide drew this up after I submitted it as a wildcat. He used a 140gr bullet to project performance. I'd use the 168gr & 175grLRAB. I think the 28Nosler is more likely to end up in my safe than the 26Nosler. It'll happen pretty soon - just gathering funds. If I build it on a 3.6" action I'll be able to hang the bullets way out and usable case capacity will be close to a 7RUM. In a 3.4" action you should be able to achieve 7STW performance in a smaller package. I'm also working on rechambering a M70 Win in 338 to a 338x26Nosler.
