Thanks for that, I'll give it a try.I saw in a review that if you loosen the hinge screw slightly it will fix the wobble making it very solid. It was opined by the reviewer that later versions got fixed being very solid I guess.
This makes me feel better. I’ve retuned to 4 valve lines reg 2 70 micro 1.5 for jsb .177 monsters. No speed changes anymore when I increase the macro wheel so it looks like a decent tune with es 2. 803 to 805 fps. Edit it is also impressively quiet again with the sarissa can I have on it.Over the years, I’ve neither found nor read any meaningful evidence of O-ring problems arising from degassing and refilling. At least not in the usual circumstances where the user does it occasionally. However I have become aware of a particular sort of heat stress and degradation affecting the seals at the high pressure end of a regulator. Speaking of the O-ring on the small end of a regulator piston and the one on the adjuster (when applicable). This heating occurs each time the regulator cycles, on account of the pressure drop of firing (cooling) followed by the pressure rise of the refill (heating) of the plenum. It slowly and gradually cooks the O-rings, so to speak, and they eventually become hard, brittle, and incapable of sealing properly.
So how does this normal, unavoidable heating effect from ordinary use relate to the occasional degas and refill? As in, does one have a disproportionately greater effect than the other? Well, I guess it just depends. For example, although a complete refill from zero clearly produces a greater temperature rise, this situation is not happening all that often. Whereas the heating from normal use is happening probably hundreds or thousands of times for every 1 time you do a complete degas/refill so my intuition is not to fret over it. Besides, it’s unavoidable that someday the regulator will need to be serviced. Other O-rings too. I mean of course you don’t want to needlessly hasten it but worst case it’s just an inconvenience when the day comes.
It took perhaps 10 years, but this is the first (and only) leak I developed on my Condor.The other place they can sometimes leak that’s super easy fix is at the check valve in the foster fill nipple. I was able to disassemble and clean it out and reassemble it… something in there was slightly rusted from the moisture from filling.
Thank you for the idea! Nice finish on the Marauder too.I have shot from many platforms over the decades blasting away with mostly Firearms. At the range, mostly very solid Concrete Benches and Benches made of Steel, however I do not like the Steel they can become resonate and vibrate too much. I have shot over Pickup Hoods, Branches, Logs you name it. I built a semi-portable shooting bench many moons ago, its seen better days. I have been shooting Pump Pellet Rifles for sometime but, never really needed a portable rest until I got into the PCP arena and wanted precise results.
So, wanting to replace the old relic that had seen-better-days, I decided to build a Portable Shooting Bench. One that was solid, stable and did not require a Hand-Truck to move it from the Pickup to the shooting location. I wanted folding legs and a bench that was large enough to clutter it's top. This specimen is a bit on the husky side but, that is ok because it is very solid and stable.
I had some flat lumber lying around the garage and found a Portable Sawhorse Online with adjustable legs and that folded up into a neat package. I still have some final work, like trim, an oval hole-handle for carrying and some stain for the wood. I took it out the other day to try it out and do a little Photo-Shoot. I was just what I needed.
Oh! The Charging-Tank... does not remain there, only for the photo-effect.
If your interested in the Design and Construction Details, you can contact me.
Enjoy,
Don

Yes the newer mags are smaller ID. The mag that came with this will fit the .253's as well but not the newer ones. The .249's are even slightly tight, just enough to keep the slugs in place. I emailed Western about it and of course they didn't reply like so many manufacturers.. Although vendors may not know the answers, at least reply. I do use Slick 50 One lube that I've been using for years on slugs and pellets.Nice test! I haven't done much with slugs yet in my SW... I did try some Zan .253, H&N Grizzly, and H&N HP's but they didn't shoot well. I was trying to decide on whether to order some .249 slugs next, so this is great info.
Do you use any kind of oil/lube on your slugs? I've seen some people recommend it but I've never tried.
(As a side note... my original mag would fit a .253, but the newer mags are smaller, and even .250 slugs are very tight now. I think they changed it to address the issue of some pellets/slug sliding forward in the mag causing a jam. That's why I was curious to try .249)
If anyone's looking (as of 11.13.24) -

I use a free app for my phone called Decibel-x. Works pretty good.No.. I don't have a db meter of any sort but to my ears it sounds waaaaay quieter...
