Burning rate is a perticulaly important factor in semi-auto gas operated rifles. The size and location of the gas port and piston are critical, and this was a factor in redesigning the M-16 in the early years when the govt bought ammo from Winchester to feed in a rifle designed for Remington ammunition. The bolt velocity went up, the reciol buffer failed, the full-auto rate was too high and failures occured.
