The 6mm Remington is my favorite 6mm. When remington introduced the 244 slightly ealier than the 243, The barrels installed on their rifles had too slow of a twist rate to stabilize heavier bullets. In the meantime the 243 emerged with a faster twist rate and would shoot the 117's better. the 243 became more popular than the 244. By the time Remington re-configured the 244 and re-named the round the 6mm remington it was to late and the 243 already had a strong foothold. Any good handloader will get much more from the 6mm than the 243.
