The original published length of the Kel-Tec P17 barrel is 3.93 inches. That has been corrected.

The length on the web site now is 3.8 inches.

The measured length is 3.8 inches.

Have you ever shot SK 22 rim ammo?

Aren’t most standard velocity 40 gr .22 LR subsonic out of a <5” barrel?

[Travis McGee]

Today I shot 22LR from my Taurus TX 22, indoor range.

From a rest, at 20 yards, (max range), the Aguila 60 grains were okay for accuracy, but about 1/4 of them showed clear keyholing.

Much worse, about 10% caused a jam because the very short brass casings failed to clear the action.

This was not a problem in my Ruger Standard Model pistol when I did this same test some months ago.

Point being, those quirky oddball Aguila SSS 60 grainers with their very short brass have to be tested in every firearm.

I posted an article where the subsonic to supersonic transition zone effects for .22 ammo are explored. A very simple experiment.

Here is a link to the AmmoLand article.
