full tune, change piston seal, airguntoyz mod, trigger upgrade to my NPAW. Shooting 1/4 groups or slightly larger using the original centre point scope/bipod/shooting table at 13 yards.Love this rifle now. Shoots better than my modded 1377
My two cents:I just recently received a replacement Crosman Venom NP from Amazon. After about 100-150 pellets the first gun was still producing 5-6" groups at 10 yards. Tried five different pellet types. The replacement gun arrived two days ago. I cleaned it and tightened up the screws. First half dozen shots went all over the place. Then it tightened up and now shooting golf ball size groups at 15 yards. This is freehand and I'm not great shot to start with. Don't know if the gun is working perfectly, but for sure it's better than the first one. My advice is to get the gun replaced if you think there is something wrong with it. If nothing else it'll help you keep your sanity.
High powered break-barrel air guns aren't for everyone Thom.For your enjoyment, maybe look into the fixed barrel GAMO CFR, with a little less power, and a lot more accuracy.

The difficulty with the underlever-type guns is that they end up being heavier. Crosman is slated to introduce one too. I really like a lightweight gun. Underlevers eliminate the break-barrel pivot as a potential problem, but not the dynamics and follow-thru required during shooting -- due to the spring or gas piston moving. I was reading CDT's site -- and he was talking about the tremendous pressures and dynamics that are involved in springers. I certainly don't know everything, but I come from a firearms BG, and I am kinda expecting the gun to shoot where I point it -- no follow-thru required. It's likely me. You are right -- it might be that springers are not for everyone. (At close to the $350 for the NP version of the Gamo CFR, I'd rather have a Marauder, even though the required add-ons are also $$$$)
Quote from: chuckinohio on July 22, 2013, 08:54:21 PM The major detriment to accuracy in my Remington NPSS, which is the same rifle as your Benji NPS, lied in the barrel pivot washers. I replaced my plastic pivot washers with Bronze Thrust Washers from the TrueValue hardware store and it did wonders. You want them to be between .062 to .065 in thickness. Before the swap, my rifle would shift groups around the bullseye at random due to the barrel locking up differently owing to the play in the barrel pivot point. CHANGE THE TRIGGER OUT, the stock trigger is atrocious, simply awful. Changing it out gives the rifle a whole new character.There is yet no parts manual for the Benji NPS -- I just DL'd the Rem NPSS parts list. Are you speaking of the Part #19 the "Breech Spacer"? These look like shoulder washers. Are the "Thrust washers" you got from TruValue flat washers or do they have a shoulder on them? Thanks for the informed Reply!!!I think I'll just have to do the trigger.

I don't believe that my heavier HW77k underlever is much more accurate than my break barrel R9, but the extra weight of the "77k" does make it EASIER to shoot accurately. Still, I use my .177 R9 MUCH more than the HW77k since I also prefer a lighter weight springer, plus I don't give up much (if any) in the accuracy department.

They aren't true shouldered washers, they taper on the outside edge a bit, more like a radiused edge, that is what looks like a shoulder on the diagram. I used flat washers, as have many others here, with great success.I do believe that Genes washers will fit the NPSS, and by default the Benji NPS rifle. If you are not motivated to grind the OD of 5/16 washers to fit your rifle, then the ones from Gene are in order.

I'm really ready to return my gun as hopelessly inaccurate. I feel unwilling to spend $30 for a new trigger; why aren't we storming Crosman's doorstep to get better triggers in these guns? To heck with their "drop test" requirements.
I was able to hold my NPS to about 3.4" to 1" at 18 feet -- resting my hand on the arm of my couch with scope. This accuracy was not acceptable to me. The Daisy 880 was 'same-hole' at that distance; plus I could hit toothpicks stuck in cardboard 50% of the time with the Daisy; 10-30% hits with NPS when it was firing well.

This way they sell you an inexpensive gun that shoots pretty good but not real good and you either get frustrated and fix it, throw it away or get something better....

Keep in mind that the Daisy 880 is probably easier to shoot accurately. As everyone has said, spring/NP guns seems to require a bit of a magic touch. I certainly don't have it. I've shot my dad's springers since I was a kid and have never been a great shot. I've had my 2400KT for about two weeks and I've found that the term "stacking pellets" is not exaggeration. At this point I'm debating whether I should give up on the Venom and get a QB79 from flyingdragon.
Yes, the weight to powerplant ratio is a real demon with some guns. You'll find that some of the most accurate springers start in the 8# range. There's a reason. A lot of us that have responded, have experienced these issues, during our "spending education" in airgunning. Yes, better rifles do cost more, and they are worth it if you don't wanna start buying different rifles. The CFR in spring powerplant is not that expensive ($250), and is proven as a very calm shooting underlever, with great accuracy. Gas strut/rams, haven't steered many of us guys...due to their expense and Quality. They don't have a long history...ya know. Guys have converted over to Gas strut/ram from Crosman, as they are cheaper to buy as a part. But a smooth springer fixed barrel isn't too hard to achieve economically.Finally. Trigger kits like are offered here, are actually CHEAPER for you. If the manufacturers supplied such triggers, you can bet it would be more than what these guys charge for their design and QC assured trigger kit.
