im thinking of either getting a 16inch cz synthetic

or getting a 12.5 inch ruger 10/22 hogue stock

just to keep things short for hunting really. im currently on a 21inch cz(toooo long)

it made me wonder at what length would all of the powder be burnt and indeed what is the shorest i can go? the reason i ask is a barrel too long is unnecessary weight and length but too short and you get a fireball

 

i have a sirocco sm11 mod going on the end its about 6 inches

 

but whats the shortest length id get away with?

from what i read before deciding on mine the powder is burnt in the first 9".

barrel length after 16" slows the bullet.

mines got a 12.5" volquartsen barrel and no complaints about that.

 

theres quite a bit of info floating about on the net, and rimfire central forum is a good place to have a browse of if you're looking at rugers.

I understand that 16" is the optimum, after that a longer barrel slows it down. 14" could be a good choice, I don't think you'll notice any difference on a .22lr between 16 or 14 - in fact I doubt you'd have a problem with it down to 12.

 

This is something I am wanting to so with mine I was thinking about going right down to 12 inch.

my understanding is 16" gives you maximum velocity, although any losses either way are very marginal.

the 16" barrel length is an american thing, its their minimum length which is why a lot of aftermarket ruger barrels, tactical solutions etc are that length,

its not to do with barrel accuracy or bullet velocity.

I chrono'd some ammo in three essentially identical rtifles a few months ago. One had a long barrel, one had a shorter one and the other was shorter still.

 

The end result was that, to all intents and purposes, the long barrel was longer than it needed to be as it produced lower velocities. Clearly the powder was exhausted before the bullet exited the muzzle. I think that the middle length barrel recorded the highest velocity, if memory serves. However, the longer barreal was certainly the more accurate of the three. I doubt that that had much to do with barrel length though.

I was informed by a Technicial advisor at Anschutz their Rifles have done everything its going to do in the first 9 inches ,

Be Very careful cutting down to 12 inches because a fraction under 12 and it becomes a Section 5

Better to go 12 1/2 inches to be safe

Also get it cut and Screw cut by a Good/competant Rifle smith

like this, have a look at the charge in a .22 sub and you will think 9" long
