Hey guys,

Im wondering, does anyone make a 12" threaded barrel for the 10/22? And how much accuracy would a guy loose by going with a barrel this short? Im thinking of doing a mod to my Marauder, and it would require a barrel, approx 12" or maybe even 14".... and would need standard threading.

Thanks for now,

Ginnz.
 
Dlask Arms makes a 12.5" bull and sporter contour barrel. They are very well made and accurate... we have a number of them and are very happy with the results.
 
Have a 12.5 Dlask sporter bbl on my Gangster Thompson build, runs Blazer perfectly. No fail to feed, fire or eject in 47 rounds as fast as you can pull the trigger.
 
the misconception that shorter barrels sacrifice accuracy only holds true to a degree with extreme long distance. In the case of .22lr a 12" barrel will have higher MV and more consistent MV, along with a much stiffer barrel which leads to better accuracy. Barrel quality is the only real important factor when buying. Dlask makes 12.5" in both a tight match chamber and a sporting chamber that will run on Blazer. NEA makes 12" bbls with match chambers. The NEA is a bit cheaper but from what I understand Dlask bbls are higher quality

I think the 12.5" would have lower MV. This is because there is not enough length in the barrel for the velocity generating powder in the cartridge to fully burn off. If anything, it would be lower MV. Although, a longer barrel is an example of lower MV as well; when the powder from the cartridge is completely burned off before the bullet has exited (friction caused by barrel to bullet while still inside barrel cause velocity to lower). I think the sweet spot for a barrel is 16".

tests done by a member here prove that his 12.5" Dlask showed higher MV over his 18.5" factory Ruger barrel. .22lr reaches max velocity in the 12-16" range, this will be different for every type of ammo. Swapping from 18.5" Ruger to 12.5" Dlask will increase MV, consistency and accuracy
 
i asked the same question awile back about the 12.5" barrel and on the imformation supernova provided i purchased the dlask 12.5". i also have a factory ruger hammer forged 16" bull barrel on one of my other .22's. they are both in hogue stocks, both with the same scope and bipods and the dlask 12.5" is actually more accurate.

Wow, really? That's very surprising. Maybe the efficiency of the ammunition might play a role in determining this as well (some ammo does better in shorter barrels and others do better in longer barrels). Maybe the barrel is coated with a teflon based lube?

So if 12-16" barrels provide the best MV, and the shorter the barrel, the better the accuracy, why does Ruger make a 20" BBL for their target models?

Yeah I didnt believe it at first. There is no coating, the reason for the higher MV is there is only so much powder in the casing, it will burn and expend its energy to a certain point before the pressure curve drops off. At this point the bullet has reached max velocity and will flatline before slowing down due to friction in the bore. My geuss for the longer barrels is tradition. Short barrels are just getting popular recently, with modern research and technology people are seeing the benefits they can provide. Some people still think theyre universally useless and would disregard a factory 12.5" 10/22. Thats how I see it anyways. But you are absolutely correct about consistent ammo, that is the other key component to accuracy. Last being the shooter
 
I wounder if the 12.5" BBL fits in a Hogue stock. Does anyone know if it clears the forearm? I might have to get another 12.5" Dlask, this time in .920" BBL. I'm quite happy with the 12.5" factory contour from Dlask. I'm going to put a Levang comp on it soon when it ships here. Still don't know if I should use a crush washer or a peeling washer, so I ordered both. I know you don't have to index those, but I'm doing it more for aesthetics.
 
Yes, please do. I would love to see how it looks. Been thinking about a build with 12.5" in a Hogue for a while now.
 
Won't be able to post one till morning but it looks great. Went with a desert tan hogue stock with 12.5" bull barrel, levang compensator and full rail with just a simple set of gen2 magpul mbus in fde for a short light weight plinker. If you check out the first page of the 10/22 pics thread about 3/4 way down the page you'll see another members black one. That's were I got my build idea.

The above testing can not be reliable due to the uncontrolable variables involved... velocity tests that comapare velocity vs barrel length, using TWO DIFFERENT barrels... will be inherently inaccurate... your conclusions, however, are basically true.

There have been a number of tests where a barrel has been cut down and inch at a time and recrowned/cleaned prior to each velocity test. The results show that IN GENERAL (not in every case)... velocity is maximized between 13-15"... Standard velocity deviation is at its lowest from 12-16"... Velocity begins to drop off marginally after 17" and significantly after 20"... Accuracy was consistent through all standard lengths from 12-20"... Inherent accuracy is more a function of quality and percision than of length.

I couldn't find the thread, but you have me curious at how you can put a full rail with BUIS on a Hogue stock.
 
note this is not my rifle but the rifle i modeled mine after. i used the same rail kit by utg but i modified it as i didnt like the full look of the side rails. i also used magpuls and a levang comp instead of a muzzlebrake. im painting parts of my rail kit in fde to match my sights and stock so im not going to post a pic till its done but this gives you the idea. cheers

I agree that comparing a single barrel of one make with a single barrel of another make isn't an ideal definitive situation.
Problem with doing any empirical testing of different barrel lengths with a single barrel is that there is a major legal issue.

Not in the factory of a barrel manufacturer.
