@Badboymelvin - some clarification. I recall the introduction of the 243 Win. My uncle purchased a Model 70 in 1961. At the time the readily available cartridges in the US were .222 variants, which in Oregon were too small for big game. Larger cartridges were 250 Sav, 257 Roberts and larger yet, 270 Win. The Savage and Roberts were chambered in short actions that required either small bullets or if larger bullets, the base protruded down into the case, reducing powder capacity. the Roberts resolved this with 117gr round nose bullets that had poor ballistics. About the same time as the 243 was introduced, so was the 244 remington. The 244 was actually a better design in that it had a shaper and shorter shoulder and a longer neck. But Remington marketers determined the market for it to be varmints so cut the barrels to 1-12" twist- insufficient to stabilize the 100 gr big game bullet.
