 Ux Ruger Blackhawk #AD758xxx
  Ive had this Blackhawk since last winter. Not alot of shots through, 300 +. Had a crooked Breech Leade taper along with a very rough looking crown. Breech seal seemed abit low so i added Threadtape shims under the seal. 
 Trigger is adjusted Out. Easily one of the best triggers i have, M34 needs more adjusting to be as good, for Me. The Blackhawk tigger is plastic with a Very light 1st stage with travel and a well defined Wall to stop on to break. Smooth Ball lockup, good open sights.
 Before reworking the Crown the Sights were adjusted much left. After reCrown it now hits near center to the right. Good after some work.
 This AG does very good 20-30 yards with HNFTT 8.7gr 4.52mm with Open sights for now, will mount a scope after more pellet testing.
 No Warmup Shots.

 Before Chrono Run, i reworked the Breech Leade and reCrowned using a Dremel 3000 and Cone Stone Bit. The breech seal shimmed with 2 layers of thread tape.
 Funny, i was expecting atleast 100+ FPS over what it is currently getting.

 This came with a crooked breech leade and a very rough crown. I reworked the Leade and Recrowned the rough crown. I also shimmed the breech seal with 2 rounds of threadtape.  This AG does Very good to 35 Yards with the tested Pellets. Open Sights are adjusted to the left some, even after having redone the Crown. Might need to recrown the recrown to get POI closer to Center. At a later time ill add a Spring Rated AO MD scope.
 This has good smooth Ball Type Lockup. Trigger adjusted out, 1st stage with travel, good wall to Stop on. Good trigger.
  Around 300+ shots in at Chrono Run.

 Some smoke left after the shot. Needs more shots to be more consistent. Also need to test more Pellet Types. Puts out Good Power.

(#1) Seems to be a common problem with Umarex/Ruger break barrel rifles.

(#2) I have seen this many times on different (model and manufacturer) break barrels. The sometimes extreme left-right offsets were all due to the front sight being rotated a tiny bit off-center (from the factory).

Only one of those rifles had a bad crown which caused large shotgun patterns. After a re-crown the groups tightened up but there was still a significant left-right offset. I rotated the front sight position a tiny amount and that made the rear sight nearly dead center for best POI.

Obviously bad crowns need to be fixed but I suggest simply checking rotation of front sight if groups are good and the rear sight is adjusted far off-center.

Cheers :-)

mikeyb,
 The Blackhawk and Airem2 both seemed to need the breech seal shimmed as the seal didnt appear to protrude past the breechface.
 I have checked to make sure the front sight is centered, had it been off center,,that would bother me. The grouping is good, just groups to the side.. i think the crown is good as i got a scope on yesterday and got 15 yards sight in done. I still need to refine sight in for 27 yards.
  Thankyou mikeyb for your reply. ExcellentWork.

 15 yards, 3 targets. The left and center target were used to sight in some number of shots. The right target is 5 shots on a 3" target.
Yesterdays 21 MPH winds coming from 5oclock position was too much for 27 yard shot groups. I got it to hit close at 27yards, but ill need to recheck on a less wind day. Will also chrono run more types to find a pellet with a lower Spread.

I had redone the breech leade and recrowned the scary looking crown.
  I think i overdid the leade as it was crooked and that made me run the dremel longer. Now pellets seat deeper than other barrels.
 I tried a few of CPUM 14.4gr and they were all over the place, from 734 to 860 FPS, im sure this has to do with the light fit of the pellets along with the deep cut leade.  This does good with HNB18s and HNBH 18.2gr.
 CPHP did good until i redone the breech leade. Stock screws have  blue locktight.
 This RAM is long and heavy, heavy cocking force, alot of action during the shot. Among the best triggers i have. Has done good out to 35 yards. Some time ago i made a 40 yard shot on large feathers with little hold over.
 I still need to get a scope on this RAM. Appears to need to be shimmed alot to get it on target.

  I tried some CPPirhana 14.4gr., they did good around 860 FPS, until i got 1 that read 684FPS.
The deep breeche leade makes it so that i need longer pellets like HN Pellets. Im wondering if the power level is good and healthy at 24 - 25 FPE for a RAM. Or is it a little Low.. anyone here know?

 Ok GTA. O r g members.
  My Ruger blackhawk.177 is making under 10 FPE does this sound not right? I've had it around 1.5+ years and it has done good and consistent in accuracy and in FPS spread not being Soo much to cause any worry of like a bad piston seal.. But the cocking force and recoil and shot report tell me it should be making more than the 10 FPE. Could it be that my seal is consistent in how much air is lost so as to still be accurate.. I have a B1022 that makes 70+ more FPS with the same pellets and it's caulking force and recoil and noise is a lot less... This Blackhawk has maybe only 1000+ shots through.
  I know there are a lot of Blackhawks around in GTA but I almost never see any Chrono numbers. Is my Blackhawk very underpowered. Someone answer please XD XP
 Excellent Work Stay Alert

Not a hawke owner and likely telling you what you know, but here goes.

The extreme spread with the ftts is tight enough to suggest it's not a seal issue.  You probably checked the breech already anyway. Likely not the piston seal either.

It's possible you have a broken spring that has settled. I had this happen to me on a gun that was underpowered but still gave a tight ES.

My 2 cents.

[caudie]

I have a Ruger Blackhawk Elite (clone of 34), it gets 14.1 fpe and has since I bought it new.  I also have 3 Ruger Airhawks and they also got about the same before I detuned them, 1 at 6fpe another at 9fpe and the third at 10+fpe.

Also I believe all my Rugers have metal triggers.  I think the Diana 34's have the plastic triggers.  I've done the 2nd screw mod on all 3 Airhawks and I know they are metal.

Ruger(Umarex) Blackhawk Elite (skeletonized polymer stock) is basically the same as the Blackhawk(classic style polymer stock) and the Airhawk(wood stock).
IMO these are approximately 14 fpe airguns when tuned to full power.

I believe there are de-tuned versions of at least the Airhawk for countries like Canada where MV may be limited to 500 fps(?).



The "Elite 2" series rifles DO NOT have the same powerplant or trigger, but may have similar Muzzle Energy ratings.

splitbeing,
causie,
mikeyb ,
 
 Thank you all for your replies thank you. I was shooting the Blackhawk yesterday and it was doing good I was just being bothered knowing the amount of FPE I was getting compared to the caulking force and shot report. The shot cycle sounds clean without much buzz or twang.
 I have a Airhawk that I bought in May of this year have yet to Chrono run. Soon I'll have the numbers, Ive been busy with other air rifles and each gets its turn with me XD.
I think the Blackhawk and Airhawk have some of the best triggers on a breakbarrel.
  I'll have to get a Spring compressor together soon,.. Thankyou for the quick replies,
Excellent Work GTA

Search for this on amazon if looking for a long enough clamp to act as an airgun spring compressor

Groz 39101 48" T Bar Clamp


That being said, a 10 fpe spring gun might be doable without one if you know what you're up to.
