Power Adjuster, SSG or Both?

[Gerard]

Regarding extended shot count having priority over power; that's certainly been my main interest with SSG experiments, or at least shot count combined with consistent velocity. My QB78D with a 213cc Ninja bottle could give me about 60 shots at around 30fpe, but I don't want nor need that much power. 20fpe is plenty for grey squirrels and is the limit for HFT, so I tuned to about 19.6fpe and get more than 125 shots per fill in part thanks to the SSG. Of course the regulator in the tank also helps. The combination delivers such good consistency that I don't have to worry about what part of the fill I'm on, just take the shot and know the pellet will land where intended.

I appreciate your easy to understand description David. I'm bookmarking this with a plus. Yours is the way I'll go with my Disco. I've already done the power adjuster with many of the parts you show. I need to turn the end cap. Did you source your end cap or make it?

You haven't been specific enough with your goals.

 

You're right, Cliff - I reckon I have not been specific enough - my apologies to all. Such are the hazards of multitasking with a male brain.

My goal is to get in the neighborhood of 850- 875 fps with a JSB 18.3 gr pellet while maintaining excellent accuracy for as many shots as I can without losing POI. "As many shots as I can" meaning at least 20, if possible. I'm not certain if this is doable or not without going in the direction a double tube set up, which I don't want to do for the time being (mainly due to financial constraints).

I thought I would start a new thread on the topic of my Discovery Mod journey, in the hopes that I can learn from others and that others can learn from what I learn..

You can probably get where you want to be. I have seen some pretty good results from the members here.

Thanks for the vote of confidence, Phil. I will be calling you soon for your good counsel!

I think the first thing you need it's a regulator...this will bring you the number of shots you want plus the shot to shot consistency...after that you can install an SSG to improve the things even better...

Funds are pretty tight right now so a regulator is not an option (for now).

An SSG is not going to get the power you are looking for.  It is difficult to even get stock 22 ft lbs without a super stiff spring in the SSG.  You may be able to get 30 ft lbs with a heavy hammer spring and valve porting along with higher fill pressure, but 20 shots will be a stretch.  Good luck with the experiment.

It doesn't sound like an SSG will be part of my mods for now. Thanks very much for the information.
