aga 62 conversion

I was hoping talk to some of the good people here who a working knowledge of the aga 62 and 3357. I have recently aquired a non functional aga. Too many parts damaged to make an effective repair so i just grafted a new crosman 357 onto it. Works quite well now with the exception of the number of useable shots, i get about 10 shots at a good velocity followed by another 30 or so shots at an absolutely useless velocity. Nature of the beast? I don't down to the meat of my post. Having dissassembled and done some minor mods internally already i got to looking at the barrel assembly and thought to myself that i could machine a new barrel and run first strike in this gun. I know there are velocity issues due to valve flow, but as ive always had to turn my guns down at the field when im running fs rounds i was wondering if they could work? Anybody tried? Can anyone forsee any immediate problems? The elevator system in this gun looks like it would be perfect for fs. Any thoughts on this in general?

Not enough metal in the elevator block to bore it out to .68 size, same problem with the feed tube. Also, because of the added "flutes", FS rounds are even longer, front to back, than a standard .68 round, so the elevator block would have to be even deeper.

Converting to .68 size has been thought of on here many times. We have come to the realization that there is just not enough metal in there to do it, without significant reworking of certain parts, which would esssenially require remaking most of the marker's front end.

Yeah ive thought of that too, im looking machining a new front block,elevator and the other associated pieces using the same design. The shop im working with doesn't seem to think it will be a problem. I just don't know if the valve will handle fs. Besides i didn't like to idea of modifing an original front block

Ok so despite everyones advice i went ahead and bored it out. Made a feed spring sytem and it is loading and firing just fine. Velocity is the issue at hand now. It is shooting around 200. Anyone have any suggestions? Weaker spring, carving the air chamber out a bit? Anyone done work with these?

Really what you need is to find a way to modify the valve for increased volume and higher flow. It's only meant for shooting tiny pellets, not full size .68 cal paintballs.

I modified my Crosman 3357's to siphon liquid CO2. They shoot real fast, just around 280 with .62 caliber paint. If you're getting 200 right now with .68, a siphon mod like that could get you up to maybe 260? I doubt you will have much luck just fiddling with springing.
