Where did you get the 7" 400 CB barrel?

 

[Will Fennell]

10mm DPX?

TeamCorbon,
Can you confirm if this is the same bullet[used in the .400 Corbon] that is used in the 10mm 155gr DPX load, and at approx. the same velocity? If so, i guess we can expect the same performance out of the Corbon 10mm 155gr DPX load....?

Thanks for your help.

 

[TeamCorbon]

Yes it is the same bullet.

 

[Brass Fetcher]

The gun was an AMT Hardballer 'longslide'.

thanks for your work, I've been wondering about the performance of this chambering.

I'm afraid it will go the way of the 41 mag, 44 spl, 10mm, and 357 sig though. All great cartridges in their own right that just didn't catch on as well as others.

 

[TeamCorbon]

Thanks!

14" penetration? 0.6" diameter? What would you get with a 158 grain LSWCHP out of a .38 Special with a 2" barrel?

Shot 2 - Remington 158gr +P LHP. Was fired through the IWBA 'heavy clothing', 4-layer denim test (12.5 ounce denim fabric was used). Impacted at '551 ft/sec' (chronograph malfunction), penetrated to 11.5" and expanded to 0.592" average diameter.

'Bout two inches more penetration in the longslide .400 Corbon.
