Take the guts out of your gun.
Leave the barrel and v-block in the receiver.
Inspect the sides/top/bottom of your bolt for scratches, dents, dimples.
Inspect the receiver for scratches from bolt, recoil spring, etc.
Assemble the bolt in the receiver without the recoil spring
and without charging handle.
Is it going back and forward smooth?
LUBE IT. Do you feel any difference?
Does the extractor rub the sides of the notch in the barrel?
Take the bolt out.
Assemble the bolt back in the receiver WITH the charging handle.
Do you feel any additional rubbing when moved back and forward?
If the bolt handle is aftermarket,
does it rub the upper lip of the ejection port?
Assemble the trigger group, assuming there are no pins lost out of the TG.
Observe the interaction bolt/TG.
If you have a KIDD charging-handle/spring/rod with 3 different springs,
you may want to try all 3.
Clean the barrel. GENEROUSLY LUBE THE RECEIVER.
Start ammo experimenting with American Eagle. It SHOULD cycle,
given you load the first round from the mag
without driving the handle forward
with your hand, but instead let it slam forward by itself.
DO NOT FREE RECOIL THE GUN. Keep it firm in the shoulder
or in the shooting sled.
Move to any other Federal bulk ammo. It SHOULD cycle.
The same with any Winchester bulk, except Dynapoint.
After 200-300 rounds, it should cycle Win Dynapoints and Win Wildcats
and most of the target ammo (SK, Eley, Fed target, the rest).
If the barrel is of the new breed (May 2011 and up)
(eg it is engraved "D.A.C. X-TREME 22LR")
it will NEVER cycle CCI ammo (Blazers, Stingers, Velocitors, etc).
Yes, the chambers are tight.
These barrels, after the break in, if the rest of the gun is ok,
will generally shoot anything but CCI.
But if you have to shoot CCI ammo,
you may try the sporter variety (engraved "D.A.C. SPORTER 22LR"),
but be aware that the sporter, as the name sez, is NOT a target barrel.
But the Dlask SPORTER will NOT chamber Stinger and Velocitor.
Also, do not confuse the Dlask SPORTER chamber
with the Ruger SPORTING chamber, they are different.
Ruger's SPORTING chamber is a large hole like a counterbore
at the end of the barrel that will chamber
almost anything (except for 9mm).
If the barrel is of the very first batches (Oct 2009 - June 2010)
(engraved "DLASK ARMS CORP 22LR"),
then you may be lucky and after breaking it in,
maybe it will cycle Blasers (but not Velocitors nor Stingers).
Also, in those old barrels, high velocity shoots best
(not slow-velocity/standard-velocity/target, nor hyper velocity,
but HIGH VELOCITY).
Barrels bought between June 2010 and may 2011
will generally not cycle CCI (not even Blazer), but
some will cycle target ammo and maybe show accurate results.
Bulk ammo (Win/Fed) will work the best.
Every Dlask barrel is tested for cycling reliability with bulk ammo (Fed/Win).
Several random barrels of each batch are tested for accuracy
whithout trying to find ammo preferences of each barrel.
These are 2 typical test groups of one of these random barrels
from the last batch of X-TREME grade.
Each group is 10-shots each, distance is 50m, very slight breeze.
The barrel was NOT tested to find the ammo with best results.
The group at left is Fed Champion blue box bulk Canadian Tire.
The group at right is SK Standard Plus.
The test gun action is a sloppy worn out Ruger
with everything factory but a trigger job.
The stock is plastic with no bedding.
Rest is usually a Caldwell DFT sled.
Optics are 24x and up (I'm legally blind).
Except for the first shot from a cold/clean barrel,
there are no cycling hickups allowed.
ntm, contact me if you have any probs.
