I keep hearing that the advantage of the 10mm is that it penetrates much better than the .40S&W. Not wanting to take this at face value I looked around some. Trying to find comparable results is tough.
On Brass Fetcher, they only have one 10mm posted, 180gr Remington JHP. One went through the block and two others penetrated 12.7' and 13.1'. The Remington 40S&W 180gr. Golden Saber penetrated between 11.5" and 12.2". So a difference of, at most, 1.5". (I considered the one that left the block as abnormal since the other two are so similar, maybe that's totally wrong)
According to Mike from Double Tap (as posted on the 10mmtalk forum):
DoubleTap .40 S&W Penetration / expansion
165gr Gold Dot JHP @ 1200fps - 14.0" / .70"
180gr Gold Dot JHP @ 1100fps - 14.75" / .68"
DoubleTap 10mm
165gr Gold Dot JHP @ 1400fps - 14.25" / 1.02"
180gr Gold Dot JHP @ 1300fps - 15.25" / .96"
So the 180gr GD penetrates 0.5" deeper and the 165gr GD penetrates 0.25" deeper.
Is a 0.25" to 1.5" difference really that great?
The DT GD expansion is much greater in the 10mm but nobody talks about that when touting 10mm.
Am I missing something? Are there more direct comparisons that I'm not finding?
I am in no way bashing 10mm. I own one and enjoy shooting and owning it. I'm just looking for data.
