Sig 10MM 180gr Ammunition tested across the chronograph in 4 different pistols.

Colt Delta Elite XE
Para Elite Hunter
Ruger Blackhawk 10MM 6inch
Ruger Match Champion 10MM 4.2inch

I would have never guessed the results would turn out like they did, Revolver vs Semi Auto!

Apologies for the ending of the video, the camera stopped recording for some reason and the audio is not the greatest. The data is still valuable.

Some food for thought Revolver vs. Semi auto...
Revolver the chamber isn't counted in the barrel length whereas the semi auto the chamber is counted in its length.
10mm has a chamber length of  minimum of 0.992" to 1.004" Max. for all practical purposes 1" shorter than stated barrel length for a semi auto.

Therefore if we look at the Glock 29 factory length of 3.78" the effective length is 2.78".
The Glock 20 has a 4.60" the effective length is 3.60".
The 5.00" barrel of a semi auto is really only 4.00"
The 6.00" barrel of a semi auto is really only 5.00"

Now compare that to the revolver with a 6.00" barrel where the cylinder containing the chambers is not included in that figure.  The revolver does have a cylinder gap that can and dose bleed of some of the gasses produce upon firing as the bullet crosses that gap and exits the barrel.

Great info Shadow, I still did not expect 1inch to make that much of a difference for the Ruger Blackhawk with the bleed off of the Cylinder Gap.

When the companies test with a universal receiver/barrel they may or may not state the barrel length but if they state the length I believe it is just barrel length and not the chamber in that measurement. (I may be mistaken...)

Some companies loading manuals list a specific pistol for their handload data where as powder companies list universal receiver/barrels.

These universal receiver/barrels are very tight tolerances that we may not see in the average commercially produced pistol barrels.  This insures that the pressure testing is within industry standards as specified by the SAAMI Institute...

Great Information! The Sig ammo seems to be some very good ammunition in the 10mm. Very consistent velocity. I don't know how much difference in velocity you get placing the chrono at 18ft vs 3ft (3ft being the norm for shotgun/handgun), but Im sure there is some, this along with Shadows info would account for the difference in advertised and actual velocity. Thank You for the video.[emoji4]

I've always had good results with the Sig 10mm ammo, accurate and fast.

I believe 3feet is way to close I have actually tried it and seen very sporadic results and I believe it was because of muzzle blast or spent powder being seen by the chronograph. I over rotated possibly to 18 feet. I say that because I did speak with the folks at competition electronics and their recommendation was 10 to 15feet.
