Sounds like a plan. I'm guessing a longer barrel isn't in the cards?
I am going to eventually get a proper chrony, as soon as money allows.Though I ask what are the potential limits of the Daisy 880? Any one that has done power modifications and chronied, how much power have you been able to get?Is 12FPE (830FPS with 7.9 grain pellets, or 730FPS with 10.5 grain pellets) a reasonable goal?Does it seem like the power plant may be able to be pushed far enough to produce 14.8FPE (950FPS with 7.4 grain pellets), the absolute maximum usable level with .177 in my opinion (beyond that you are getting a little close to the speed of sound with 7 to 8 grain lead pellets). For that matter would it be possible to reach even higher power (using only heavier pellets)?The most important question is how far the 880 has already proven itself capable of for power after modification. As that would give reasonable answers to the other questions.I am fairly sure that 12FPE is a reasonable goal, beyond that I am not sure what my goals should be, hence the question of what has been done and chronied.
And the 880 has a lot to offer if you do not mind doing some low cost simple work on it. There are a good number of 12FPE+ Daisy 880's around now. You really are not likely to ever need that much power though.
There is more power to be had. I'll find it. I don't know how much more with basic tools and no machining of expensive parts, which defeat the purpose of modding a $40 AG.
How loud would the 10+fpe 880s be? Say on the Pyramyd 1-4 loudness scale?The more I read about the 880 the more I want one! But I'd need it to be reasonably backyard quiet for intended purposes. Thanks!!

But I'd need it to be reasonably backyard quiet for intended purposes. Thanks!! I'll be honest and admit I have no idea what the Pyramyd 1-4 loudness scale is. I assume it is from the blog? I really don't follow that. I get my reviews from real users here on GTA before purchasing something new. If it is from the sight itself, I just never noticed it. My loudest 880, the 14 FPE .22 carbine sounds like a very loud stick snap in the woods. The kind of snap you hear deer hunting. The loud snap. The .177's are really not THAT much louder than a stock 880. The stock 880 has a pretty good "snap" to it when fired.

You were telling everyone that "lots" of them exist, now you are questioning if it's even possible?
Good point Rob. I USED to have a chrony. I lent it to one of my only friends and he shot it with a crossbow. He will replace it, but it may tke him a while. I have yet to chrony each mod individually. I need to do this. There are interweb claims that the hammer mod adds FPS. I do it. But I have to question how it does anything. If you look at how an 880 fires, the valve opens and stays open until you cycle the bolt. Now this hammer mod is supposed to work by letting more air out. Which to me makes no sense as the valve does not open and close upon firing. It just opens. PERHAPS it helps by clearing a little more unrestricted room for air to flow out smoothly, as in less turbulance. I have my doubts this mod actually does anything personally. Something to check in the future. But to the point. Yes 12 FPE is achievable in .177. I did it once. I have built 2 14 FPE .22 Daisy's. One is my LW barrelled 880, my main hunting weapon. The other is in a 901 Rob/Bigtinboat generously gifted me. Although those internals were in an 880 already. Both of those were built in the spring and were chronied in the mid 660's with a 14.3 grain pellet. After snow flies i'll be spending more time on the 880's, 901's and 35's making great hunting weapons. Right now my free time is consumed hunting with my 2 .22 880's, my .22 901 and my 9.5 FPE rifled barrel Daisy 35. There is more power to be had. I'll find it. I don't know how much more with basic tools and no machining of expensive parts, which defeat the purpose of modding a $40 AG.
Thanks guys! As I mentioned, loudness is a consideration for me when it comes to hot rodding an 880.

Though it is back yard friendly. The pumping noise of a stock 880 is louder than the muzzle blast, though when shooting it it may not sound that way. And the increase with power mods is not that great.The big thing about power modding is that you can use fewer pumps to produce the power you need.

I am glad to know that 12FPE is possible with 7.0 to 7.9 grain pellets in .177. I knew it was easy with 8+ grain pellets, just not the more "standard" weight ones. Would I be correct in assuming that is on 10 or 12 pumps??I had only seen definite reports of 12FPE with heavier pellets in the past. I could not point to the threads at the moment, though I am sure you could. And I no longer trust many of my past results as I have since learned more of the variables that could effect the accuracy of using sound as a way of measuring the velocity of a pellet (hence why I want a proper chrony, eventually)This tells me that 14FPE is a reasonable goal, if everything is pushed to the limits.My understanding of the hammer modification is that it works by opening the valve more quickly, thus allowing the pressure to reach the barrel more quickly, before the pellet has traveled as far down the barrel, as well as giving a more complete opening thus reducing the turbulent flow and improving the air flow into the barrel. I could be completely off, though that is my understanding.

I could be completely off, though that is my understanding. Well to be honest I have little interest in further testing of 7 grain pellets. I hunt with CPUM'S. I demand accuracy from a hunting rifle. My average shot as well as my range is 18 yards. If I can't make 1 ragged hole with an AG at that range, It WON'T hunt. And I have yet to find a light pellet that will do that from my 880's. I know you love Winnie domes, me not so much. Out of all of my 880's, 901's, 35's etc, I only have 1, yup ONE 880 that will shoot winnie domes into one ragged hole at 18 yards. So I use them for rough sighting in, and testing purposes only. I hunt with 10.5 grain CPUM's from the box. As for the hammer mod, opening it quicker does not make sense. With the way a Daisy fires, pull the trigger, the trigger clears the hammer and activates the spring which then in turn opens the valve. And it opens immediately. So to say the hammer mod gets the valve open while the pellet is still not too far down the barrel is simply illogical. The pellet won't move, period until the valve is open. So that portion simply can not be true. Less restrictive air flow....possibly. I seriously have my doubts that that particular mod does anything. But I'll test it out for sure this winter. Also in my thought process is this. Since day one of the 880, Daisy has taken the time to machine that little groove in the hammer we are filling. Even back in the day before all of the restrictions added to reduce speed. I simply can not imagine Daisy spending the extra money/labor/tooling to make such a simple part more difficult to make. But hey, who knows I have been wrong before. Point being it would be easier to just cast the part and NOT machine the groove the valve activates from. David, I could swear that a year, year and 1/2 ago you were posting what you said were chrony numbers, both before and after you sighted phonebooks and sound as your numbers sources. If nothing else, your mods posts made it sound that way.
