The performance data for the .270 WInchester are very balanced. It is a highly accurate cartridge that is quite pleasent to shoot. Nevertheles, this cartridge, which is based on the case of the .30-06 Springfield and was introduced in 1925, is not a cartridge for really large or even aggressive animals. It remains a cartridge for light to medium game from roe deer through chamois to moufflon. The .270 is also a good cartridge for use at maximum range in the mountains. However, the cartridge only has limited suitability for really large game.
