Maybe that's the norm, but with that water taking up valve your essentially over pumping. The reason it's still dumping all the air, like you said "needs to be pumped to accept a pump" would explain it still doing a full dump. Have you tried shooting it to a full 8 several times, say 3 times, then on the 4th time to 8 pumps, shot it then cock it and shoot again. See if you have air left in the valve.Very interesting Rob. I'd meant to say that the gun needed to be cocked to pump (by design)...I tried to find it to correct but didn't find it fast so that will need to waitA relatively small amount of water could occupy a high percentage of the valve volume. The Fluid was definitely wetting the probe and being drawn back into the single shot tray when it was pumped and I wiped it away as I was shooting the strings. At least what was not sent through the barrel. I also appreciate the idea of checking for accumulated unexpeled air after a few full power rounds. I will be doing exactly that when I get to shoot again. The gun will be stored a few moments vertical before each shot and shot in the same barrel up position to try to expel what may be in there out of the valve.Thanks for your input, It completely makes sense as a possibility. But I do really hope those numbers hold though.

Received mine in .22, it was a little oily, but not swamped in strange liquid.
How easy is it to make this gun a .25?
I have a .22 and at 13 pumps it shoots 14.3 at 800fps. The air valve has been opened up same as 13XX Crosman. Regards, Tom
Decided to read the manual tonight... 8 pump recommended maximum LOL

Nice. Looking forward to more info. That muzzle piece...How is it secured to the barrel? Grub screws or possibly glue or a tight fit? Also, what's the diameter of the barrel? Looking forward to some accuracy and Chrony results.

Also, what's the diameter of the barrel? Looking forward to some accuracy and Chrony results.I didn't read the whole thread, but it's actually .462. the end covered by the plastic endcap has been turned down. To remove heat the plastic and pull straight off.
Well, I just couldn't resist and eventually bought one in .177 caliber under the ARTEMIS Brand which, as far as I know, is just the same as the SPA and SENECA ones. It's a really nice and quite powerful piece of "all-wood-and-steel" MSP air rifle and deserves the "modern pumper" qualification we've been talking about on GTA.Now, I allow myself to ask you for some informations/opinion, as you've been shooting this rifle for a while : - I felt pushing the pellets with the probe in the detent chamber a bit hard. This ended with disformed skirts with another rifle (a Webley Rebel clone) at the expense of its accuracy. Did you notice the same ?- On the rear sight, I'm confused with the windage adjustment device : two opposite screws that don't seem to have any influence on the adjustment itself. I just do it with my fingers, once the screws unscrewed. Then I screw them back cautiously so the rear sight blade can't move, but it looks a weird method.- I need installing an LDC as the rifle sounds, to my opinion, like a .22LR rimfire when pumped more than 4 strokes. So I ordered an adapter but this one requires the front sight to be removed. The gunsmith in the company where I bought the gun and the adapter didn't remove the front sight, and said it can't be done without damaging if not destroying it. I surely won't do that I can't even be sure wether it's in plastic or in metal. Did you try removing it and did you succeed ?At last, but I shouldn't confess that, I'm unable to use the 10 rounds magazine... Pellets get out of it if I happen to succeed pushing them inside, and I'm afraid I might have distorted the retaining spring. Err... may be I'm going to look for a tutorial for semi-morons on the Web .Best regards, Yves
