I’ve replaced the breech seal and the barrel o ring, but no improvements. For those of you getting 30 shots per fill, was it always like that? The dealer I purchased it from said this sounds normal and there is a break in period.

Help with taipan vet

Shouldn't have to do that.
.25 shorty should get an easy 30 shots at 43 FPE.
Kev, I would consider sending it back to the dealer.
Shouldn't have to troubleshoot and fix a brand new gun.

I tend to agree. I had planned on a installing a huma reg and plenum, and while a new reg and and some adjustments may well get things right, its frustrating that it wasn't in working order out of the box. Dealer does not seem super interested in helping, just told me to shoot a tin and things should be good. Also told me there was no o ring on the barrel after I sent the schematic. When I pointed out that there should in fact be one there and asked if they could send me one, he said they don't have any parts for taipans right now. I've found the o rings online and will get some, but feel like I'm being brushed off. Not trying to turn this into a dealer rant, just want to get this little gun shooting right.

At this point, it sounds to me that either the tune is significantly off, or there is a valve problem. Even if the rifle was not regulated, there should be a hammer spring setting that would avoid this problem. Unfortunately, it sounds as if your dealer is either ill equipped, or uninterested in helping. If nothing else is gained from this experience, you will at least have narrowed by one, your list of acceptable dealers. Most European makers have a U.S. distributor, or master dealer that is trained and qualified for parts and service work. I'm glad the Taipan is such a robust and generally reliable rifle, as it doesn't appear to benefit from such a structure. It is a simple design, and there are qualified air gun smiths who could get it right, but as you said, you should not have to do that with a new rifle.

Send it back ✌ 
My impatience/curiosity got the better of me while waiting for the dealer, so I went ahead and pulled the factory reg and swapped it out with a huma I had. Immediately saw better results. Not sure if the numbers in red on the factory reg are the set point, but mine was labeled 134, which seems kind of low for a .25, but I'm not sure. I put the huma at 140 and started testing. I am now getting around 28-29 shots at 870 or so, which is right where I want to be, at least to start dialing in accuracy. Maybe the factory reg was bad, or just gummed up (there was a lot of oil/dirt in there). Also, way quieter. Anyway, happy to be at a better stating point to tune this gun. Thanks for all the help.

Is that Huma already broken in or brand new?
That's a pretty decent initial string, nice work to figure it out..

My guess, the Taipan reg is fine, just needs cleaning, definitely should not bave been gummed up. It would be interesting to see how it performs if cleaned. I would bet it is ar least equal, if not better than the Huma.

Huma is brand new, maybe 80 shots through it. I have no reason to think the factory reg is bad, but maybe just needs cleaning. The markings on the huma (understood that they may not be dead on) are just easier for me to figure out where I am regulator wise.

Yes, those markings are estimates, at best. You just have to pick a starting point and see where it shoots. If the power plateau puts your knee set point higher or lower than you want, you might want to make a reg adjustment.
