Socrates I get 1204 fps out of my 360PD with Corbons 125 grain HP's.
brassfetcher got these results with:
Quote:
Cartridge : 9x19mm Luger Speer 124gr +P Gold Dot JHP (Part # 23617)
Firearm : Glock 26 (3.5" barrel length)
Block Calibration : All depths corrected (From 11.2cm @ 599 ft/sec)
Shot 1 - Impacted at 1215 ft/sec, penetrated to 14.3" and was recovered at 0.502" average diameter.
Shot 2 - Impacted at 1196 ft/sec, penetrated to 14.4" and was recovered at 0.509" average diameter.
Shot 3 - Impacted at 1218 ft/sec, penetrated to 14.3" and was recovered at 0.514" average diameter.
Shot 4 - Impacted at 1216 ft/sec, penetrated to 14.4" and was recovered at 0.494" average diameter.
Shot 5 - Impacted at 1216 ft/sec, penetrated to 14.4" and was recovered at 0.503" average diameter.
Here's an interesting site I'm probably the last one to see. Some of the .357 Mag. velocities seem a little slow in the shorter barrel lengths, but what do I know?
A fully loaded .357 out of a carbine is nothing to sneeze at.
The reason that the velocities probably seemed low is that the shooting was done from a TC Encore rather than a revolver and the barrel length was probably mesured differently. My guess is that the chamber was counted in the barrel length of the encore wheras it is not counted on a revolver. Thusly, I'd think that the velocity of the 3" encore barrel would be more analagous to that from a 2" revolver.
In order to get consistent results, we opted to use a platform which would accommodate barrels of any caliber - a Thompson/Center Encore No. 1842. A gunsmith was commissioned to create 11 barrels (calibers tested such as .38 special/.357 magnum used only one barrel) which would each fit into a single housing, yet allow us to chop the barrels easily. This means that we could directly compare calibers regardless of mechanical issues (such as whether there was energy loss due to a cylinder gap or activating an extractor) and as such constitutes an 'ideal' performance. One note: in every case with the T/C Encore the length of the barrel was measured from the end of the barrel back to the breech face. This is how semi-auto pistols are measured, but revolvers are measured as the length of the barrel in front of the cylinder gap. Take this into consideration when comparing calibers using our numbers.

Indeed. As we say right on the site:
Awesome, can't wait!We're getting geared up to do additional tests on .327 Magnum, .41 Magnum, and 10mm here next month.
