*ExpHP -- Police
round only
From 50 feet, the TFSP ammo had 1 - 1.5"
groups-- not bad for bullets traveling more than twice the speed of sound!
Note: My Glock 31 (4.5” barrel) could only manage
2200 fps with the 60 grain TFSP.
The RBCD Platinum Ammo is designed for high
energy, bullet fragmentation, instant energy transfer and limited penetration. Energy
provides the ability to do work such as disrupt tissue and/or penetrate
barriers. These rounds reliably cycle auto pistols and even do it with a moderate felt recoil. Refer to Handguns Magazine, Apr.
2001 for more information on this ammo. RBCD Web
Site
As you can see, the 357 Sig
doesn't base penetration on just one cartridge brand. And there are some 357 Sig rounds that have mild penetration characteristics and others
that have slower, quieter velocities. As the 357 Sig
catches on, I'm sure there will be more cartridges coming out to fill various
niches. I'd like to see some factory downloaded 357 Sig ammo that equals full power standard 9mm rounds.
Specially made "police only" 357 Sig ammo
is now available from Winchester.
