Has anyone chronographed .22LR out of a 3.5" barrel.
Made a 3.5" out of a skinny barrel MKII Ruger as a dedicated host 4-5 years ago.
And earlier this year ended up with a MKII 22/45 someone previously had cut to the same length from probably 6", and threaded. Previous history unknown. If you've chrono'd rounds using this length or close, I'd appreciate seeing the numbers. |

Ballistics By The Inch has.
http://www.ballisticsbytheinch.com/22.html Their main testing was in increments of whole inches, but they also include chrono data for a variety of firearms including a Walther P22 with a 3.5" barrel.

What were you hoping to accomplish? The Ruger Standard Model 4-3/4 is so nice as is.

I have yet to chrono 36gr HP in my 4" bbl suppressed MkII, but it might get close - so I could understand going to a 3.5" bbl to be sure. https://www.dropbox.com/s/xi4grc0q5p...64613.jpg?dl=0 |

No worries at all; just thought I needed to help carry the torch for the OP maybe.
![]() Being able to 'upgrade' bulk 22LR to Subsonic is addictive, I do confess. ![]() |

Kinda amazes me that subsonic bulk isn’t available. Less powder, lower cost. Guess it would cut into their profits concerning their lower velocity stuff.

Yes. Isn't it funny that sub-par performance makes a load into "special purpose" ammo they can charge more for? Been going on with CCi Green Tag pistol match and other folks' match products for decades.
