I took my NAA Mini Revolver in .22 Mag with the 1 5/8” barrel out to my company’s ad-hoc firing range for some afternoon fun. I measured the velocity of six different factory loads using my trusty chronograph- with quite surprising results. I expected there to be a great difference in energy between the loads, especially comparing the supposedly hot 30 gr. JHPs to the supposedly under loaded 50 gr. JHPs. The surprise is that the average energy for all the loads differed by only five fpe, ranging from 87 fpe to 92 fpe.
Here are the averaged results:
A. CCI 30 gr. TNT JHP- 1151 fps (88 fpe)
B. CCI 30 gr. +V JHP- 1183 fps (92 fpe)
C. CCI 40 gr. JHP- 1015 fps (91 fpe)
D. REM 40 gr. PSP- 1016 fps (92 fpe)
E. CCI 50 gr. Gold Dot- 883 fps (87 fpe)
F. Federal 50 gr. JHP- 897 fps (89 fpe)
Note that visible portion of the bullets in loads B,C & F are identical in appearance (all owned by ATK), using a belted ring with a small JHP opening. The different weights are achieved by varying the overall bullet length.
The bullet used in A looks just like a 125 gr. .38 Special Gold Dot, just scaled down.
The bullet used in E looks like the shallow JHP used in the 158 gr. .357 Mag Gold Dot. It has been discontinued by CCI, but can still be found on some smaller dealers shelves.
The Remington PSP bullet looks like it came from a .22 Hornet load.
It looks like you can please both the light/fast camp and the big/slow camp with the above loads since they all have essentially the same energy.
I will do some water expansion / penetration depth tests in the near future.
In case anybody is wondering, I decided to load the Mini with the 40 gr. Rem PSP for “combat” use when I left the range. I strongly believe that any gun is better that no gun, so the Mini accompanies me when a larger weapon would not be appropriate.
Please comment.
Thanks,
Hunter
