I am thinking of putting a DLASK barrel on my SR-22, but not sure which length to go with. The 12.5" in SR factory contour or the 16.5" in bull (.920). i will also be adding a 2" compensator. I like the 12.5" for the look but a little worried about how much velocity I will loose with 4" less barrel. I am trying to accurize it for the long shots at gophers out here on the prairies. Does any one how much velocity I would loose going with the shorter barrel??

I would go with the 16.5 if I were you considering your desired use. You will need that extra velocity for those long shots. The 22lr will start to loose velocity somewhere in the 14 - 16" barrel length range. I have a 16.5 fluted -0.920 Dlask with Levang Compensator on mine and it shoots like a dream. The only thing you sacrifice with the 16.5 is light weight and some manuverability. It is a bit heavy with the bull but, it does help with shooting. If you do get the 16.5, get it fluted because it would be really heavy with a bull non-fluted.
 
Just a stupid question about barrel change on a SR-22 (I don't have a SR-22 yet) what about the barrel support block if you change the barrel for one with a different diameter?
 
I would not change the stock barrel on the SR-22, as it is the most accurate barrel of all of the 10-22 i own ( 6 )... JP.
 
I agree with Caramel, sr22 barrels are dam accurate with decent ammo, you can get a replacment for them so not to have a bull barrel, and the suport block well thats a debate on its own weather you need it or not, probably just to insure put one in, dlask sells .920 barrel supports to replace the old ones, as for how much you will lose, well how far is a long shot in your world? I shoot 100 yard with a 12.5 no problem on a custom 1022 and 200 yards with my 16.5 on my sr22, if you want max everything dlask makes a 20" barrel and green mountain makes a 22" bull barrel, make the sr into a rimfire sniper rig ;)
 
Thanks for the responses guys there much appreciated. My SR 22 is not the most accurate 10 22 I have owned, which is why I am looking for some mods. Maybe I should explain that a bit. When I got my SR a year a go, I took it out to break it in and ended up with a 1/2" ten shot group at 50yrds. Which is great but the problem was I was using winchester hollow point ammo out of an ammo can and have no idea which kind of winchester it is. Since then I have tried 10 different types of ammo. Ranging from yellow jackets to target/benchrest, and the best i can do is an inch at 50.
 
Hey tachead is your barrel a normal longtitude fluted or the new circular one. Dlask only lists the circular one.And do you find that your compensator actually helps accuracy?? I was thinking of putting on a levang or an XB4. What kind of groups do you get at 50 and 100yds with the Dlask set up??
And does any one know who sells green Mountain barrels in Canada and which one is considered more accurite, the dlask or GM??
 
bits of peices in Vancouver carries green mountain barrels, Jerry at Mystic precision caries a few different 1022 barrels as well, Ive had good luck with both, hopefully wanstals gets there tac sol dealership soon and they will have them in canada as well

Mine is the older square flutted one. The Levang seems to tighten the groups up a bit as others have noted also. The only problem is it weighs like 4ounces so, it adds a bit of barrel weight to an already heavy rifle. The groups I get wont help you much because my SR is highly modded. There is barely anything ruger left on her. Lets just say it will compete with some peoples benchrest rifles. The Dlask chambers are cut to make the best out of cheap bulk box ammo like Federal Champion 525, Winchester Dynapoint GT, Winchester 333/555, exc. But, you shouldnt shoot any CCI/Blazer ammo out of a Dlask especially Stingers or Velocitors. They are cut too tight for the bullets that CCI uses and wont chamber fully and can cause case rupures and explosions. That recomendation is right from Dlask too. I havent owned a GM barrel yet but, have heard good things about them. I went with the Dlask because of all the good reviews and the fact that they are cut for cheap bulk ammo which I perfer to shoot. I would speculate that the Dlask barrels would outperform GM with bulk pack ammo. Heres a pic of my rig. Its set up as a long range rifle in the pick. I took the full length rails and covers off now and just have the small Dlask rail on the bottom for the vertical grip and a half rail on the left side to mount my fashlight for night shoots. That shaved some unnecessary weight off the front end.

Have you taken into account the extra weight? My friend added the bull barrel and it added a tonn of weight. To the point he doesn't like it for shooting standing. If all your going to do is shoot prone/bench. Then your fine, but if you free stand, the extra weight might be a pain! FYi

You dont have to go bull though. They come in factory contour as well. Theres always a trade off with everything. Bull barrels are more accurate generally but, are heavier. Its all what you want to build the rifle for. And, tell your friend to quit being a wuss. Mine as is in that pic is still only 10 pounds and I have a 3-9x40 scope, very heavy rings, one of the heaviest stocks out there, a 16.5 bull with comp, and three rails and protectors on it. If you want light with a bull buy a 7 inch carbon fiber handguard, no rails or vertical grip, light stock, light compact scope and rings, and no compensator on the barrel. I would guess you could get it to around 7 pounds even with the bull.
 
Tachead that is one awesome looking piece of kit. Looks like the only stock parts left on it are the forend and reciever side plates. Interesting looking bolt, almost looks like a carbon fibre pattern finish on it.

Techead I totally understand however I bet you shoot more than 75% using your bipod.

I do shoot off my bipod a lot because I built this rifle for long range but, I am using this rifle exclusively for grouse this year. It is on the heavy side at 9lb10oz in its present form but, well balanced and still fine to carry in my opinion. If you are going to carry it for long ranges and always shoot offhand I would build it lighter though. Especially if weight bothers you. Really, if you want a light weight rifle, the SR22 is the wrong way to go.
