I believe 18’s as well.
Please don’t assume when you get your new Impact that the factory or the dealer has actually “tuned” it unless you paid them for that service. Even then i would be suspect. I have bought 9 new FX guns over the last 3 years. Half of them came through our best known FX dealer. None of the guns exceeded nominally operating status when they arrived.

Same experience. Mine was definitely not tuned to my liking when I got it either. I was able to drop the rear reg by 35-40 bar and it’s shooting the same speeds just about but everything is working a lot less. 90-100 shots per fill at 125/85 reg1/reg2 shooting 18.1g about 900fps.

Ordered!
Thanks Firewalker

That is just to COOOOL" put that on the back of my 12' pram.

I set up my .177 D34 for sub 12ftlbs, was (& still is) wonderfully accurate. Kept 99% of my shots within 25 to 30 yards, or there abouts. Worst thing I ever did was shoot it over the chronograph. I had no issues but found power eventually dropped to just above 8.5ftlbs... I did replace the spring but probably could have kept it in there and aside from slightly better trajectory with new spring, there was no real difference in results on game and/or pests in my area... talking smaller critters like pine squirrels, chippers, hosps & maybe occasional rabbit if the cat didn't get to it first. None of these are particularly tough.

I recently purchased the Hammer and have been sighting it in using the 550 grain slug. I have very good accuracy at 25 and 50 yards, however at 75 and 100 yards there is significant drop with the 550 slug. Anyone else using the 550 slug? For longer distances should I go to a 350 slug?

Ballistics! Try reaching further and see where the effective range stops.

Jim. thats why i picked up a couple extra SCBA bottles for $50.00 each on Craigslist. I spend the time working in my shop on fill day and fill them all up. good for months that way ! LOL

Just got a 30 CAL Challanger PRO LB (Gen2) with the adjustable REG / Hammer.

Curious if anyone has tuned these yet and what settings they are running. REG came in at 170 BAR and Hammer all the way out. I'm getting 990 with the AEA 50.5 Grain pellets currently.

Also has anyone slugged one of the Long Barrel Versions. I've read that the recommended slug is a .303 but curious if this still applies to the Long Barell Version. Currently have some H/N 54grain HP slugs and they are .301 Thanks for any help / guidance

So far very impressed with the build quality. Going to get to go out tommorow for some accuracy testing.

The ARH soft spring with OEM guides has a good shot cycle. I think this spring is about 12fpe. If you don't use the steel top hat that might reduce the power slightly. A TbT delrin short stroke spacer is another option. The shot cycle is a little snappier but the air volume is reduced and this can lower velocity slightly.
I've tried different springs and found that going too low in power can increase lock time and affect accuracy. For me 12fpe allows for accuracy at 10-50 yards while not disturbing my sight picture much.

My cheaper drs synthetic hangs if not beats the other 2 for accuracy

Here, let me get that for you...

It’s important to know that the rear sight on Sheridan/Benjamin/Crosman pumpers that are pressed on with shims that are putting pressure against the soldier joint between the receiver tube and barrel. Add a scope with a Sheridan or Buck Rail mount and more pressure is added. Soldier joints can deteriorate or time. That pressure can help the barrel to separate from the receiver tube. I’ve seen many that have. Difficult to repair. I see the rear sight as a hindrance to the design of these rifles. A peep sight is far superior anyway. If adding a peep sight or especially a scope, the rear sight should be removed. IMHO borrowed ad.

Nice detective work!

I started with a Benjamin Marauder pistol (Prod) and a hand pump. It only stores 60 cc of air and can only be filled to 3000 psi so it is a great gun for hand pumping. I found the stock tune a little low on power and turned it up some and it's taken 17 squirrels for me so far. If I hadn't added an Avenger next, I might still be hand pumping. For small guns with modest pressure needs I found it works fine. Others are more tolerant of hand pumping and do it for much larger guns. Another variable in my mind is target shooting versus hunting. Hunting requires relatively few shots so hand pumping is not bad. Target shooting can involve many more shots where hand pumping gets old.

My other reason to comment again on this is my recomendation of a 22 caliber. I think it is the best all around choice but I've been enjoying my P35-177 and it's taken 15 squirrels for me so far. Pellets are even cheaper than 22. The regulator came set to 125 bar in my 177 versus 135 or more for the 22 and 25. It also uses less air per shot. I can get close to 100 shots per fill with the 177 whereas the others are closer to half that. So if I was hand pumping I would seriously consider a 177. It has adequate power and it's only real disadvantage for targets is the very low bc of the pellets makes it more wind sensitive. But if you are hand pumping the low regulator setting makes it possible to fill to a lower pressure and the greater shot count keeps you shooting longer before refilling.

I contacted my dealer this morning and he said that it should have the 580cc bottle and he told me to come in and he would swap it out. Thanks for all the advice.

You may want to ask if he could swap out the whole thing so you get a true "Sniper" in a "Sniper" case. When and if you ever go to sell it, these little details may become important!

I used to buy/sell/trade a boat load of powder burners. Now that I look closely at the 777s and after owning a rebuilt 717, I would say that a 95+ 777 without original box and all inclusions would be worth $400 if it was rebuilt with a good exhaust valve. Probably add $100 for a good condition complete box (papers, pellets, tools, lube, patches and rod) with a good condition Daisy shipping box. I suspect the only difference in complete takedown between a 777 and 747/717 is that on the 777 you must raise up the metal rear sight all the way till it will flip forward and loosen the screw that resides inside till the clam shell comes apart. After that it is all the same.

I'm going to keep both of these 777s and order an Ambi grip for one. I can shoot either LH or RH and that will allow me to shoot 2 at once or shoot LH or if a LH shooter wants to shoot with me or if a righty wants to shoot informally.

Welcome to the best AGN @

Thank you, sir!

After more research I’ve settled on getting a scuba tank (easier to source and cheaper) to fill the majority of a weapon’s tank, and then use the RovAir to get up to 4500psi. We’ll see how long this setup lasts me.

Yep, that's what I do, zero it and then start shooting. If you want to do something first, clean the barrel, otherwise, mount the scope, zero it and start putting some lead down range. You may find it's shoot at or near what you want right out of the box. Plus, if it's zeroed before tuning, you will be able to see shifts in POI and/or accuracy as you go, which may help you decide on the proper tune for your use.

Thank you, just ordered everything.

A leapers UTG bug buster 3-12x32 scope is the perfect size.

Did you see this thread about AAO?

Airforce - Texan SS AFRICAN AIR ORDINANCE?

Hello, I'm wondering if anyone has tried AAO SUPER VALVE with the heavy hammer and magnum spring? If so I'd love to hear about your findings. I have a LSS and an SS in .457. Information on either rifle with the AAO setup would be greatly appreciated. Thanks

Well think I found rite speed for slaps in my p3 & hm1000x! P3 reg set at 130 ,speed 980-1000fps. Got my first 1” group at 100yrds! Zeroed my scope at 35yrds and less than 1/4”, at the distance. Also I clean slugs and lubed them. The raw, I cleaned barrel before we went. And after 4 mags finally got it to holder group 1/4” at 35yrds. It’s shooting slaps at 940 -950fps. At 100yrds 1” groups! Wind was 7-8mpa. I love both these guns. And my Texan 457 held its own like usual 1” group at 100yds. Exciting day for me. This chronograph has made such a difference in tuning my rifles. Now after getting my buddy’s raw shooting good. I’m trying to figure out how to talk my wife and let me get one. After buying airacuda max & p3 in last couple months!

Thanks for the suggestion, SC; I'll take it under advisement. Pretty good idea, I might save enough time to actually PRACTICE a little.

Correction- I might save enough time to actually practice A LOT.
