So you may or may not recall that I picked up a Pitbull Texas Edition (aka a Pitbull AKC with scope, bipod, and other goodies).
I had trouble right from the start.
Eventually after several months I eventually convinced Pitbull to take a look at the gun. They determined that the regulator and regulator gauge were bad, and claimed I was essentially shooting an unregulated gun. I don't really buy that the regulator was so bad that it was like it was not there, but that is beside the point. It looks like they also replaced the front gauge aluminum that was scuffed when I first got it, which was nice. Paul reported that the regulated gauge was reading 2700 but cautioned that it might read 2800 psi for me. It did, coincidentally. It is 2800 to 2850. But I am looking for 8-10 regulated accurate shots for Coyote hunting, so if I am ultimately able to get that, I'll be happy.
Anyway, still hand pumping, pumped it to 4500 psi, tested with 135 grain BT LDC from Griffin. The results weren't that great, in fact, from my perspective, worse than before I sent it in...but more on that later.
Here are the results.
Graphically:
After calling Paul at Pitbull air, he said they tested it with 50 rounds after the repairs, but without a chronograph. Paul told me they don't have lab coats or beanie hats at Pitbull airguns. Too bad, really. Nothing wrong with being methodical from my perspective, but oh well.
Even so, while I paid shipping to Pitbull air, they spent time, energy, and 50 rounds of lead as well as return shipping, so that was also nice. A plus for pitbull air.
Anyway, so I cleaned the barrel, pumped it back to 4500 psi, and tested with the 145 Gr. Benjamin Extremes, and got better results.
It both cases(135 Griffin and 145 Gr Benjamin eXTREME), the power spring was turned back 3 full turns from full tight.
I'm new to this, but I am guessing I was wasting air on the 135 and need less hammer spring. Either that or the fouled barrel had more of an effect than I would have guessed.
Anybody got some guidance?
Meantime, I need to buy a compressor. This hand pumping takes too long to dial in the gun.
All in all, I've had better luck with a used crown .25 I picked up and modified. Eventually I may end up disassembling and rebuilding this pitbull airgun, especially if I don't get anywhere with an electric compressor and chronograph testing. On the other hand, this pitbull did drop a coyote so I am still happy about that. Guessing a .30 FX crown or edgun leshiy 2 would have as well.
