The problem is one of physics and volume.

The .270 is an odd caliber, with odd bullets. It’s kinda the 120-140gr reputation that built the mystique, along with Jack O’connor in large dose.

The 6.5mm at .264” and the 7mm at .284” have produced remarkable cartridges over the years. The heavy for caliber, mild recoil best guns in 6.5x55 and 6.5x54 have stayed a lot of game, especially in the 160gr options. Same with the 7x57 with 175gr options. Thank the Europeans with their long throated barrels and ample action length with heavy for caliber bullets for all of this.

I would rather have a 7x57 or 7x64 than a 270. Same for 6.5x55 over the 270.

I’m a hunter first, a fine firearm collector second, and a “high tech latest thing” guy dead last. Beautiful guns tend to come in beautiful, proven, traditional European calibers so that’s where I land.
