If you like the fast twist 7 and all you want is a fast twist factory rifle. I seen some of the Remington long range hunters in 1/8 twist. Finally they are catching on. I think if I'm buying a new rifle I would probably go 28Nos if I could find it in a 1/8. Then 7PRC but 26 inch barrel. Then 7Rem. If building it would be really tough but maybe still custom 28 Nos, and then maybe a 7/300win practical or something like a 7/300 PRC but with only having to neck down the neck. But then if I spending that type of money to build a full custom it's probably going to be a 338 IMP 30 degree Lapua. For now it's my 300RUM is my easy long ranger next to my short action cartridges like my 308 or my 7mm-08.
