Pistol to Carbine Handload vs Factory Chrono Test

Wreck-n-Crew

New member
Been looking forward to running some test using various hand loads in a carbine and a pistol. Common thinking that the velocity increase in the carbine will produce a measurable increase in velocity percentages over faster powders and some factory ammo. So i set out using 3 of the four powders i have on hand to see just how much increase is possible.

Its common knowledge that some of the slowest burning powders are used for rifle and some of the fastest burners for Shotgun and common pistol calibers like 9mm, 45, and 40 respectively. Between those lies a variety of powders that are slower burning and load many calibers as well as shotgun. once again... common knowledge...

Powder choices were Unique, Red Dot and Power Pistol. I loaded enough for a five shot string for use in both the pistol and the Carbine. First mistake was made here with only loading 5 each. I failed to account for errors and other unforeseen issues and my ammo ran short. Some strings were only 4 in lieu of 5. The biggest issue is the Power Pistol muzzle blast was causing Chronograph read errors and velocity readings in the 300FPS range. I had to move it back to 15ft (rifle setup distances) to prevent the errors on the pistol test. Wow...all I can Say. I wasted too many rounds doing this...lesson learned.

Some notes worth mentioning:
The hand loads all were coated bullets and were not my own. I have not had to chance to do a batch or i would have used my own. So improvised I have

Note on loads: None were max with the exception of the 9mm Red Dot load and it was at max according to one published source. some Data has Max at .2gr less than What I used. So

Warning, Some Data Using Alliant Red Dot Smokeless Powder in this test exceed max load data in SOME published data and any use or copy of said data in your firearm is not advised. furthermore i am not responsible should anyone cause harm to themselves, their firearm, or anyone else who may be in the vicinity should a failure, ricochet, over penetration, or any other type of loss as a result of using said load

I had three firearms with me as I was testing some Power Pistol Loads and Red Dot Loads in 10mm with the Chronograph. The 10mm was not a part of the reason for the test but I figured id throw the result in anyway. Also Used was a 44 Magnum Carbine with only one Factory load and I also threw those in the results because of the interesting velocities recorded. The 44 magnum was rifle length at 20"

Man that Power Pistol was moving!

Final notes:
I haven't crunched the numbers but i dont see a large percentage gap at first sight between slow and fast powders. Maybe the numbers will show a smaller increase than i thought.

I also noticed that contrary to some reports that coated bullets are a smidgen slower than a FMJ or Plated round but I did not see that. Also those 6.2 gr 9mm loads in the Carbine were at .357 velocities. it was funny how you could hear the bullets smack the target with a thud. Awesome day.

I took a lot more away from this day than just the 9mm loads. looking at the 44 mag speeds was surprising from what i thought they would be.

Also the Power pistol 10mm loads were not hot at all. Actually on the low end but they were loud! Well it is power pistol. Also the light Red Dot 10mm loads were quiet...like 9mm quiet without the concussion of a standard 10mm round.
