This is about the same time they brought out the .280 Remington, and failed on that launch also. The .280 has the opportunity to beat the pants off the .270 Winchester and a corporate decision doomed it to mediocrity. It was loaded to much lower pressure than it and the guns it was chambered in would reliably handle. The reason they gave was to keep the pressures lower for use in the fairly new Model 740 autoloader, however this gun was available in .270 WCF so their reasoning held no merit. What they did right on the .280 was they moved the shoulder .050" forward to keep it from chambering in any .270 WCF.
to my knowledge the 740 or 742 was never chambered in 270. Primarily because the 270 was popularly reloaded with 4831 powder. Case rims were torn off. When they were making the 7400 that chambering was a problem especially ially with foreign made ammo.
