    ‘glad to see you figured it out. 

    With these less expensive guns, it’s sometimes hard to tell if it’s just that the gun’s not that accurate, or if it’s something else.

    Do you still have the stock trigger in it? If so, you might consider upgrading that; it makes a world of difference.

Yep, it groups really well and consistent now. I didnt realize that I should keep the elevation and windage adjustments within a certain range of their adjustments or I would lose accuracy. Nor did I realize the scope and mounts needed to be checked more every 200 shots or so, Mine lasted about 600 shots before the scope mounts loosened. I am new to the sport, so shimming the rear scope mount was required to allow the scope internals to be more tightly held by the springs. The trigger is absolutely great, as I did the bearing,spring mod the day I got it.

    My Benji NP XL1100 was shooting 3″ groups at 10 yards with my best artillery hold.  I removed the barrel shroud and found that the threads on the muzzle cap were cross-threaded.  The pellets were probably clipping, and little slivers of metal were getting into the bore.  I haven’t shot it much since, but it’s shooting much better even without a careful hold.  IIRC, with the shroud off it shoots about a 3/4″ 5-shot group at 15 yards.  It’s still not very loud.

    Its been a while since I updated this. I have since added Hawke low Scope Rings with a Hammers 3x9x32AO scope. For a short period of time after dialing in my Venom I was laying down some impressive groups. Approx 1 inch at 15 yards, which I consider decent.

    Now keep in mind I have about 750-900 shots thru this rifle since new at which point I had gave it a good going through and trigger work. Today i tore it down to give it a look over since my groups had all of the sudden went from 1 inch at 15 yards to 5 inches.

    I picked up some 5/16 brass washers and milled down the OD to fit in the barrel recess, the ID was perfect as is. Well upon teardown every stock screw was loose despite being Blue Loctited from new when I went thru it initially. Even my new scope rings were already loose? Less than 150 shots thru it since the scope rings and scope install. Granted I didnt Loctite those when I had initially installed them. I Blue Loctited them upon reassembly this go around.

    I then cleaned the barrel, this time I ran a nylon bristled bore brush thru it which I had never done before, I merely mopped it the first go round 900 shots ago when new. I gave it 3 pull throughs with the brush, then 3 pull throughs with a mop soaked in WD40. It came out dirty the first 2 pulls. Then I regreased the cocking linkage with WD40 white lithium spray, and use Red high pressure grease on the linkage guide, as well as the barrel bolt when I installed that.Red Loctite on the Barrel bolt,stock screws, and Blue on scope rings.

    I also found O Rings at Lowes that fit the breech seal, which was badly leaking. No leaks now after replacement.

    It looks like its gonna rain tomorrow so I may get to do some shooting and see how it turns out.

    I have a crossman nitro venom 177 cal.   I keep it at my camp, i use it to thin out the chipmunk population.  Mine is VERY accurate, i have it sighted in at 20 yards and it will shoot a 1 inch group all day long.  The pellets i use are crossman premier hp. 7.9 g that i buy at walmart.   The gun is stock with an old BSA reflex scope.

    OK, I had some time to re dial in the scope after the teardown/mods,rebuild. This is what I ended up with.Mods are listed in above post.

    Crosman Premier Hollow Points
    5 shot group
    15 yards
    Shooting off of front rest, it was windy and my paper targets were moving ever so slightly.

    That’s about how I do with my Crossman Shockwave .22. I have done the trigger job, cleaned the barrel and added a Mantis 3-9x32mm AO scope! Also a teardown and lubing! Made a huge difference!!
