Ordered it from Pyramid Air and received free 2 day ground shipping and 11% off. $177 to the door. I must say for the price its appears to be a pretty decent rifle. Checked out everything from muzzle to butt and no issues noted so far. Ran a weed eater string swab through the barrel to check for obstructions and commenced to shoot a few pellets through the new girl for function purposes. Started off with Crosman Premier heavies at 10.5 gr. Cocking effort seems really smooth with little to no friction felt through the entire cocking motion. At this point I'm leaving the supplied 3x9x32AO scope off till I can put a tin or two of pellets through this baby to break in in. Preceded to put about 50 shots through it without any noticeable dieseling or even smoking. I was shooting inside my garage at about 20 feet into my ballistic putty trap. After about 6-7 shots I had it dialed in to the 10 ring of one of those cardboard paper Gamo targets. And this was with standing off hand shots. This rifle is impressive so far. I was expecting a rough cocking cycle and excessive smoking/dieseling but so far its smooth as silk and somewhat quiet. Mind you I was in an enclosed two car garage. As far as the trigger goes it seems to break quite nice. My Wheeler beam trigger pull scale says its consistently breaking at 3-3.5 lbs. Not bad I would say. although the second stage has some considerable creep to it. Im going to let things wear a bit before I do any trigger work.
I know this model has probably been discussed here to the point of exhaustion, but I thought why not whats another thread going to hurt. And besides I was hoping to get some opinions, and suggestions, on what pellets seem to consistently shoot well through everyone else's ACCU17. I don't have a lot of money to waist on pellets. Im not a fan of pellet samplers either. Thinking of actually doing some long range paper punching with this rifle. 100-150 yard type stuff. Will be getting a comp mount, hopefully a decent 4x16x40 30mm mildot scope and home making a adjustable kydex cheek riser. Similar to this one I'd say, but more contoured to the original cheek rest thats molded into the factory stock...http://www.tacticalworks.com/tacticalblog/category/karsten-adjustable-cheek-rest/ (http://www.tacticalworks.com/tacticalblog/category/karsten-adjustable-cheek-rest/)
Im going to search the forum, but has anyone done any trigger work to the SAT trigger to eliminate that second stage creep? Im assuming any trigger work or disassembly of this rifle of any kind will result in the void of the factory 1 year warranty. I just don't think I can wait a full year before I tear into this thing, especially after reading about peoples issues with these rifles. Ive read a lot of people having issues and a lot of people not having any problems at all. I hope I'm the latter. So far it seems to off to a good start! Thanks for reading this long az post!

My first reaction to your post was that 100 - 150 yards is a big ask for an Accu (CFX) You might prove me wrong but maybe not.
The trigger job is very simple. Just take the screw out at the rear of the trigger and replace it with a longer one, about 1 mm longer but trial is the best measurement. If it is too long you can't pull the trigger. With a bit of adjustment you will be surprised at how good the trigger is.
Once adjusted I use a dab of hot glue to keep the screw from turning with vibration.The best trigger upgrade I have done is to take the original trigger screw out and drill and retap for a 3 mm screw. The extra thickness seems to help. Usually Gamos are over greased on the spring and cleaning that off can help with general shooting.
Sometimes the plastic muzzle break can be a detrimental to accuracy and the muzzle end of the barrel that has about 25 mms not rifled and that can cause accuracy grief. If you think that needs attending to then search the Gamo gate under Challenger and read what I did to my Challenger. Challenger is just a CFX - Accu with different stock.
The Gamo underlevers are worth playing with because they can be very good guns.
One more thing; Gamo use a brown coloured varnish, for want of a better description, in the new barrels. It takes a solvent like turpentine to clean it out and a fair bit of it. If it has been used a wet patch will look as if it has rust on it. Turpentine will not bother the seals but if it gets into the rotary breach it needs to be cleaned out or it will diesel badly. You can put it into the barrel with a syringe successfully.
PS. My CFX likes JSB 8.44 grain pellets and my CFR, likes H&N Barracudas 10.6 Grains and my Challenger likes RWS Superdomes 8.4 gns. All fundamentally the same gun so I suspect there is no short cut to deciding what your gun shoots best.

Novagun,
My thoughts exactly, but when I was researching this accu177 to see what everyone thought about this rifle, I stumbled upon this guy "EdgyReviews" on Youtube. This guy has 3-4 videos about his accu117. Couple of them are about how his gun has broken and he's had to send it to Gamo for repairs and such. Anyway he seems to like shooting at those ranges and he's issued a challenge that I'm going to take on! Here is his video issuing the challenge. https://www.youtube.com/watch?v=J6nE46tuAdI&t=4s (https://www.youtube.com/watch?v=J6nE46tuAdI&t=4s)
Thanks for your reply... I'll buy those pellets and give them a try.

Well Im on about shot 180 and this thing has been dieseling/detonation since shot 40-50. It will settle down and then start back up and pop and smoke for 5 or 6 shots every 20 shots or so. Like i read, these thing must be greased to the max! Theres no way this is good for the piston seal. *(&^ Gamo would save thousands if they would learn to lube these things the right way!

Stick with it and get it sorted. It will be worth the labour.

Most definitely! I have a lot of work to do with this challenge. Thanks for the advice

If by "pop" you mean "bang," it sounds like the piston seal might already be bad. I don't think a good seal would allow enough grease past it to start intermittently detonating 50 shots into break in. An occaisional undersized pellet might also cause the symptoms you describe.
Good luck!

I was starting to think the same but it hasnt banged in about the last 50 shots now. I wish i would have busted out my chrony and recorded all of this. I will get it out and at least see what fps im witnin now. Could still be a issue there. Ive only been shooting from 20 feet so far in my garage. The pellets seem to be hitting my pellet box with authority. I know that doesn’t really mean anything.

Hello Cliff,
This is a couple of months old thread but I wondered how the ACCU was doing? I have had the same problem with the occasional shot going subsonic. How did yous turn out?
