    Went to the range again today it was cold and miserable with a bit of a breeze.  Fingers were just cold enough to where it was difficult to to load the pellets in the gun so I did not stay long.  Still i did manage to find the sweet spot for the not sorted and not lubed JSB 18.2 .22 pellets.  You can see by the group sizes how it went.  Five shots per group.  Yellow is at 75 yards red is 100.

    The one marked factory setting is at 910fps for the largest group and got mixed up with my first go at 845 in the center of that group.  I made all of the velocity adjustments with the hammer spring adjuster on the bottom of the gun turning it two clicks clockwise at a time till I hit 845 which showed promise so I did one click to get to the 835fps which it seemed to like best with these pellets.  Sorry the 980 is posed to be 890 dyslectic a bit?

    I did clean the barrel first it has quite a tight choke on it. So these groups were shot on a recently cleaned barrel.

    Oh, and fergot to say this thing is a bit snappy with it's report when shooting.  It's a loud high pitched snap that I would think would make it not too back yard friendly in it's stock form.  There are baffles in the moderator but things are still a bit noisy.

    Thanks for suffering through it, dont look to bad considering the weather. What direction was the wind coming from in relation to your target and how fast (mph).

     BTW  A bad day at the range beats a good day at work!

    The range is near a bluff that is 300-400ft high so wind changes in all directions constantly never the same for more than a minute or two.  Today was no different wind at 0-6 or 8mph and would be my guess and in all directions.  I tried to wait till the most calm moments , like the 2-3mph stuff, to shoot but it did not always werq out that way.  You can see the results of the wind at the bottom of the bottom target as I tried to shoot a group twice but gave it up when the wind picked up or changed.

    Werq is a four letter word that I try not to use anymore. ;^)

    I am filling to near 250bar and fill the magazine five times so pretty much a hundred shots but I have the 580cc tank I stole from my Impact on it at the moment.  Impact is waiting for the shroud I messed up to return from FX.  Remember also that I was constantly lowering the velocity from 910fps to find the sweet spot for these pellets.  So at the most accurate 835fps velocity I would get more than a hundred shots, with this tank, by probly 15 or 20 by my guesstimate.

    Wow, that's much better than I thought it would be! Do you or anyone else know where the barrels come from and are they choked?

    I read they are LW barrels and they look to be the part as they match others that I have.  They are choked nice and tight for sure.

    Nice! I can appreciate a good choked LW. Is it heavy? and how is the balance in your opinion (for off-hand or kneeling). This thing interests me more and more lol, just trying to rule out BR-only type guns now.

    It is 6.3lbs or 7.75lb depending on where you look but with a scope, rings and the extra large tank mine is near 10lbs according to the bathroom scale.  With the 580cc tank the gun balances right on the trigger.  I feel the gun is well balanced and holding it offhand or kneeling feels quite stable to me and I have balance problems so that is saying something.

    I am not sure how much this means as I was getting too many fliers and upon closer inspection I found that the barrel is bad.  The last 3/8ths of an inch is way chewed up.

    Thank you for sharing this.  Mine is on the way back to the dealer for a functioning issue.  When it comes back, I’m going to scope the barrel with my Hawkeye borescope with right angle eyepiece.  I hope mine does not look like yours.  I don’t want to have to start arguing over what is considered a bad barrel.  As we all know, what one person considers bad, another may feel is acceptable.

    Mine shot very well at 25 yards, but I did not try the full auto mode.

    Be careful I used my borescope it glossed over the damage and made it look much better than it was.  I had to take a still shot with the borescope and magnify it 2x to really see the damage and at that setting the resolution is not that great. The camera set on super macro shows it like it is.

    I'm getting another LCS this week as a personal gun, the last one was a loaner for review. I found that the best accuracy came right after a really deep cleaning of the barrel. Hopefully I won't have to work the barrel much but being I'm keeping the gun I may do some work to it out of the box.
