I'm in (western) Oregon.
Which post are you speaking of on the GunAndGame forum? Are you talking about my first coyote? I had to use a roundball on that one, so the next one should go down faster due to the use of a much better boolit. Along with nutria and rabbits, I have also taken a corsican ram, and a wild boar with this 909 rifle.
It does seem like it may be a bit more difficult to get a misfire with the 2tube 909 guns compared to the 909S judging from my own rifle. I had tested mine once before, and couldn't get it to go off.
After watching the video, and hearing that a 2tube 909 had gone off when "strum tested"', I tested mine again. I almost stopped trying to get mine to go of because I felt like I was just beating my rifle up. Then it went off right before I was going to stop trying. I then got it to go off again in no time, at the same angle I got it to go off the first time. Play around with the angles, and I bet yours will go off as well.
The 909 is very easy to dis-assemble (though I haven't dared try to remove the valve in mine, and have no reason to). A beautifully basic/genius design reminiscent of the Colt 1911 in terms of simplicity. I will send you a link to some instructions.
If you are talking about the slug in the picture with the calipers; yep that is the 207grain Devastator. I have a stash of them, but they are in .452. I am saving them for my next bigbore air rifle (which has a .452 barrel).
How do I like the work Leroy did? I don't like it at all, I LOVE IT! Four or five full-power shots within 6-10fps of eachother is not easy to come by in a bigbore airgun. With 240grain T/C Maxiballs, I shot a 4 shot string where every shot was between 693, and 699fps. Very nice to have when hunting multiple animals, and not wanting to drag the pump around for the ride. His current tune offers about 20 more fpe than my rifle, which he tuned about 2 years ago.
As far as bigbore air rifles go, the accuracy really cannot be beat. My best 3-shot group (that I have measured) to date is .45 inch center to center at 50 yards. That was shot off of the steady stix while sitting on the ground out in the field. Shot with Mark Whytes .45Slim design sized to .4545, cast in very soft lead. I may have tied that with the EPP/UG design, but haven't measured many of the groups I have shot with them .
Most all of my target shooting has been done off of steady-stix, though I have recently switched to a mono-pod for faster acquisition on incoming coyote. The steady-stix can't be moved around easy enough while hunting.
This boolit may prove to join the ranks of the .45Slims/EPP/UG's when it comes to accuracy. Shot off the mono-pod at 50 yards kneeling on both knees. I had changed the zero from roundball, to these 235 or-so grain HP Lyman #454424's (an obsolete mold that is very hard to find). Things got a bit wobbly for shot #2, which you see over there all by it's lonesome. The lone shot really aggravated me, but my ride showed up right after I shot this group. I will do better next time. The small squares are %97 of .5 inch (printer was set-up to copy at %97 size: DOH!).

They look like they were designed specifically for air rifles, even though they were actually designed to improve on the performance of roundball for Cowboy Action Shooting. Followed by a couple of groups I shot after a days hunt. They are very typical groups, as they are the only two groups I shot that day (off the stix, of course). .6, and .9 inch center-to-center. EPP/UG's match the speed of roundball, while being a little bit heavier, and probably benefiting from a better seal.
