That will get a squirrel out of a tree!!! I had to shoot a gray 3 times today with the .22 to get him to fall, dam there tough animals. Might have to do a carbine .25 for squirrels around here. The SSG is a billion times easier to tune than standard spring pocket gun dont you think Scott. I was going to go out to the shop but decided id drink a beer instead plus its DAM cold out there lol. Tomorrows another day Ill figure it out.

And I can attest to this.  I was on the line when he 'tortured' that gray.  LOL!!!!!

I haven't done any accuracy testing, we are up to our knees in snow right now.... but for a different reason I am working with a newer version of the SSG as well.... I am using a version which effectively does the same as yours, but the guide is not fastened to the hammer.... It looks like this....



Think about is as the way you are doing it, but without the guide fastened solidly to the hammer, it just pushes against it.... The weight of the guide travels with the hammer, and no energy is wasted accelerating it and then having it crash to a halt against the end of the tube.... All it does is pick up the weight of the very light collar just before hitting the valve stem.... In addition, it doesn't stick out the back anywhere near as far, nothing to catch your fingers with, but you can still get a cocking indicator if you wish.... The added advantage is that you don't need as high a cocking force, as no energy is wasted.... The first time I used this, I had a choice of less preload or getting more energy from the hammer and being able to use a heavier pellet (guess which I picked)....  ;D

This is a fairly easy one to implement if the end cap gets threaded 5/8" fine...:) a 10-32 nut threaded onto a guide that is 3/16" and leaves enough clearance inside the end cap nut. I am building one of these next...:) Having a set up all ready running in the rifle leaves me plenty of parts to take good measurements.

Also, on the gen1's, 10-32 guide rod leaves enough thumb clearance( and does not require putting your thumb on the bolt handle). Look carefully, as *YOUR* thumb may be larger than mine and thus at risk...LOL
cheers,
Douglas

If you want a smaller nut, you can drill out a 6-32 nut and re-tap it to 10-32....

Hi Guys,
               Maybe a stupid question but it won't be my first.  In following this and playing with my Prod, it seems that I might have an extra .5 in available for the spring.  Is there an advantage to having a longer spring?  From reading your posts more coils, less cocking force, but same hammer force?  Am I following correctly?

TIA

Yes, a longer, lighter spring, for a given preload, will have less cocking force.... It's the AVERAGE spring force you need to get a given power.... The limit will be the spring going coil bound, or being too light to do the job....

I built my new version of the SSG yesterday, using a hammer I had laying around. preload was about 4.5lb
it works really well, however the hammer is super heavy, and now even heavier due to the extra hardware on it. Bounce is back due to mass increase.
I will make a much lighter hammer today or tomorrow, and test it again. It works really well, and if you were to add a little "button on the end of the guide, it's a rear cocker as well.
Another upside I found, is that when you tune it, you can easily move the hammer, to check how much dead play there is between the valve stem and hammer face.

I have also threaded the hammer cocking pin, so I can remove the whole thing by only removing the rear cap.

Opened up the stock valve and barrel port then added the SSG, tuned and got around 28 shots but My crono has only 1 working IR light so I got miss reads  I deleated the miss reads and the above string is whats left of string. several first shots miss read so string starts high and looks like it has no curve but it does LOL. SSG are being made now and will be on website shortly, I will also be offering a SSG install and tune all in one for big savings.

Thanks Bob! I know they will be a hit. This will also make my job easier , as you know tunning a SSG is simpler than a standard marauder.

Good solid 25 shots (more than 3 clips) within a 4% ES at 46 FPE average.... looks great to me....
