Question for Saeed

I addressed it to Saeed, possibly others have tried it. Have you ever cut off small amounts of a .22 rimfire barrel to find the length that gives the highest velocity? Think I've heard it's about 16 inches?

16" has been shown to be the optimum length for maximum velocity in tests undertaken on the 22RF just as 21"-22" is for a shotgun.

Have done it for center fire - 223 I think, but not 22 RF.

Might be a project for the future.

I have found an old BRNO 452-2E rifle.

It has a 25 inch barrel.

I think this might be a good candidate.

I will gather different ammo - standard, HV and ultra velocity and see how it goes.

I have seen charts on the net if one cares to search for them.

Not as fun as doing your own

This is our 223 Remington test with progressively shorter barrel.

I am gathering the ammo - I wanted all ammo to be of the same batch number, and probably need several thousands.

I would like to do a comprehensive test.

I will post details later.

Many years ago a man by the name of Calfee, did extensive testing and wrote a great article for "Precision Shooting" magazine. As I recall velocity did not decrease until he got below 16".

Please look at the Rim Fire Forum.
