After reading another thread here it got me thinking powder burn rate and how it affects recoil mainly in handgun calibers. I have always thought the faster the powder the more recoil a given load would have. But now I think its more the speed of recoil that is what is more noticeable.
It also seems that calibers in semi autos prefer the faster powders and because of the limited which to me makes the gun feel more snappy during recoil. So in a .45acp and a 230 grain bullet going 850 fps to me feels more uncomfortable than a.45 colt with a 250 grain bullet loaded with a slower powder but still traveling around 950fps.
But where I'm confused lately is lets say you load up the .45 acp with x amount of powder and you load the same charge in a .45 colt the acp still feels more snappy. Is the difference firearms being used? the actual weight of the firearms being used? Or am I just totally wrong on all accounts?
thanks for the help
