yes, the perpetual debate goes on, and maybe i was truly bored, but two recurring themes we continually see:
The .40's recoil is much harsher than the 9mm:
below is a table i found from winchester, i entered the XD weight (lbs) and it calculates recoil in ft-lbs for some of their standard ammo
Firearm, Ammunition, Bullet Wt, Powder Wt, Velocity, Recoil
XD9, 9mm 115 gr, 115, 6, 1190, 4.21
XD9, 9mm 147 gr T Series, 147, 4.8, 990, 4.59
XD9, 9mm 124 gr. +P, 124, 5.8, 1180, 4.76
XD9, 9mm 127 gr. +P+, 127, 6.2, 1250, 5.63
XD40, 40 S & W 180 gr., 180, 6.2, 990, 6.39
XD40, 40 S&W 180 gr. T Ser, 180, 6.4, 990, 6.40
XD40, 40 S&W 165 gr. T Ser, 165, 6.9, 1140, 7.22
Thoughts? appears that in generic ammo you're picking up roughly 50% more recoil with the .40. Interesting that the 9mm in +P+ doesn't kick as much as the .40
The .40 makes a bigger hole
Obviously this is true, but how much bigger?
.40 inches = 10.16 mm
Bulltet cross-sections (w/o expansion, need some more data...):
Pi * (10.16/2)^2 = 81.07 square mm's
Pi * (9/2)^2 = 63.61 square mm's
81.07 / 63.61 = 1.27449
Conclusion: the hole made (entering) by a .40 is 27.5% bigger than that made by a 9mm. Not as big a difference as you may have thought...
Ok guys, i know this debate is beaten to death..... but might as well get some numbers rather than hype involved....
merry christmas to all!
