I'm considering getting a 953 for backyard outdoor plinking. I'd keep my 853 for indoor target, it shoots great and I don't want to mess with it.

Is there a way of modding the 953 to get about 700 fps with it? I have a PAL so I'm not the least bit concerned about registering it - I would.

Seems to me with this kind of accuracy, a cheaper pester and plinker is not possible.

moltogordo, just wondering why anyone with a Talon would consider any other air rifle for pesting? As a side note how do you register a Talon that can be fitted in so many ways with different power sources and calibers of barrels? It just reminds me of going to register a truck and telling them it may have a large diesel motor one day and a small gas motor another day.

here is a power mod i found.
http://www.network54.com/Forum/79537/th ... +some+help
not sure about 700fps, more like 500fps but i have no numbers on this.
i found your and the 54 post while researching the gun and mods myself.

what do you guys think of the 953? i am thinking of getting one. how much do you shoot yours Rene?

I did the mod to the piston end as mentioned on the 54 forum, and shot around 515 fps. Next I drilled out the hole in the valve spring retainer,"I don't remember to what size, approx 1/8th" or larger, and got a little over 600 fps. The only problem was the accuracy fell off at that speed so I replaced the valve spring retainer and left it at 500 + fps. The accuracy returned.
I assumed the barrel twist was optimally set for under 500 fps. If you do buy one and decide to mod the piston end, be careful to leave enough room so the end doesn't hit the valve retainer. That,s what I did at first, by rounding it up. I didn't do any damage as I was just touching it enough to leave an imprint on the JB weld. I didn't try a stronger hammer spring, but that might be another approach. If there was a way to put a one way check valve in the compression chamber, you could pump it twice, that would surely give you the power that you want. The accuracy loss that I experienced might have just been my gun. Cheer,s

For that big a jump in power, I would think you need to be able to pump more than once.... I'm not sure if the pump linkage (or even the sear) would stand the strain of twice the pressure in the valve.... but that would be my focus....

The wall thickness of the compression chamber is quite thin. That could be another point to consider.

Im just doing the piston fill mod right now. I was thinking of maybe clipping a coil or 2 off of the valve spring. Has anyone tried that?

The piston fill mod is the only feasible option for increasing fps on this platform.

How does clipping the valve spring help? The valve already dumps the entire volume of air as is from the factory.

I didnt know if it dumped the whole valve or not, thats why I asked. Im also curious as to how enlarging the hole of the valve spring retainer increases fps. Although minute wouldnt that be increasing volume? Thus negating the piston fill procedure?

I doubt it would do much, if anything at all. The 953/853 design is already optimized for a single stroke operation.

You can cock the hammer and fire it again without pumping to see if any retained air is left in the valve. Retained air never happens in a properly functioning 953/853.

I just complete the piston fill mod on mine the other day, it's now throwing 'Hobbys' at 510-515 fps. I also removed the barrel band to help the barrel to float more, these little rifles really are accurate at 10yards
