I spend a considerable amount of time recommending the Taipan Veteran simply because I want others to experience the satisfaction of ownership I have experienced with mine. I like simplicity...hate workin' on stuff, (after a life time in maintenance) like my guns to to shoot the "good stuff" like JSBs and also the "more affordable" CP domes...my Daystates do well with both without touching anything except poi but power settings are fixed on Huntsman and Wolverine...one 360* ccw turn of HA spring on my Veteran shooting 18.13s @ 870 and I get 830 with decent accuracy and more shots per fill with CP 14.3 domes, easy repeatable and simple to fine tune, just rezero scope. The "white board" groups, the bottom left was the Veteran after sitting for a couple weeks at 250b first 5 shots with CP domes...the other brown board is a typical 18.13 group, been doin' it for a couple of years now! BTW the bottom R white board group was first 5 shots with .177 unregulated Huntsman also sitting a week or two...JSB 10.34s, all groups at 31yds. Guns with power adjuster knobs like my Bobcat work well and easy to adjust but translate into more O-rings and are more complex...I'm out on them...although had no issues to date just like the Veteran platform better since I found it. I've recommended the VetView attachment 303381View attachment 303382 before and will again...good luck whichever one you choose!

What Veteran configuration do you have, standard/compact etc? How many shots do you get per fill shooting the 18's at 870?

Ideally I'd like to keep my eyes open for a pre-owned gun to save a few bucks. There was a nice Veteran standard that just sold a couple days ago, you snooze you lose.

If the Uragan was easier to adjust on the fly it would probably be my number one choice. I'm leaning towards another bullpup style rifle and I like the super high shot count on the Uragan, plus everyone seems to love them. With that being said, I know I can't go wrong with a Veteran, which was my immediate first choice. Now I've narrowed it down to the Veteran standard or long, RTI Prophet, or a Cricket variant. Cricket has the least interest currently.

I'm looking for external adjustable "power", meaning regulator and or hammer spring adjustment, at least 60 shots per fill at 30fpe+, a trigger as good or better than my Maverick, and enough power on tap to shoot the 25.4 pellets in the 850-900fps range. The last part is why I haven't been looking at the compact variants, I'll need the extra barrel length, but shooting the 25.4's well is my lowest priority. I plan on shooting the "standard" weight 22 pellets most often.

When my Maverick was 22 caliber I shot the 25.4g's primarily, so I have a lot to use up. Thank you to everyone for their input so far, I greatly appreciate it!

I have a standard I got 3rd hand and haven't touched the the reg. Not sure on shot count say 70 with 14.3s.

Just last week I had my prophet out and was trying different velocities. I ended up tuning it to shoot 25.4s at 940 fps. If I did the math correctly that should be 49.8 fps.
At that I shot 90 pellets and did not drop off the regulator.

I have to add the FX Maverick into this equation. If has two externally adjustable regulators and an indexed adjustable hammer spring. The indexed hammer spring adjustment allows repeatable velocity adjustments as opposed to more primitive screw adjustment systems, which can lose their position after a few dozen shots. This system is used by the Cricket II Tactical.

I owned a Kalibr Argus for about two weeks before returning as it was a nightmare trying to get a tune within the published specs. The constant disassembly to adjust the regulator was my worst experience with an airgun ever, even worse than the AEA HPBP, and that's saying something.

That might work with some guns, but not with others. If the fixed or non externally adjustable regulator pressure is too high and reducing the hammer spring to the minimum still produces too much velocity for what you want, you are stuck without modding or adjusting the reg. One example being the Uragan 2 in 22 Cal. It shoots heavier pellets superbly, as good as any PCP gun I have been able to shoot so far, but it will NOT shoot 14.x grain and lighter pellets below the sound barrier with the hammer spring turned all the way out unless you take the gun apart and adjust the regulator. Another example is the Gauntlet 2 in 30 cal. The regulator is set a 2800 PSI and with the hammer spring screw backed out all the way, vs all the way in only gives a velocity variation of about 100 FPS - 820 to 920 fps with 60 grain slugs, which is not enough on the slower end for some people.

Hmm, I can get between 873 to 1015 fps with 44.8 grain pellets in the Guantlet 30. Maybe more adjustment would be good, but I don't see myself ever wanting less power in a 30 caliber than the roughly 75 fpe you get on low power setting. That 30 fpe difference or so is enough to exactly double the shot count on the air tank. Pretty sweet for a budget rifle. My "problem" with it is needing an allen key to adjust it though. Seems like making some kind of external knob/wheel to turn the hammer spring would have been a very easy feat of engineering at almost no additional expense.

My AEA Challenger Pro 30 has a lot more adjustment range. In addition to coming with two hammer springs and ability to adjust the regulator (have to degas and remove air tank though), it's got the AEA "power wheel". The wheel alone provides a huge range of adjustment. I was surprised to see I can shoot pellets in the 600 fps range if I have it turned all the way down. So if you like a gun that has a big range of power adjustment, and an easy external way to do it, AEA is looking pretty good to me. But again, the slowest I shoot pellets is high 800s to low 900s anyway, assuming the gun is capable of doing so.

You make an excellent point for this topic. A set "tune" of regulator pressure/hammer tension/hammer weight/stroke length can only get you so far without needing to adjust the regulator. If your desired set-ups are within reason, probably can get to a pretty efficient combination of settings without adjusting the regulator, otherwise, will need to adjust reg.

Since the Veteran was mentioned a couple times I'll give some examples of it. My .20 Vet does VERY well with just hammer tension adjustments and the 13.73grain @ 800fps or the 15.89gr @ 915fps. No regulator fiddling necessary. For a .22 Vet I've been happy with extreme spreads using the same regulator pressure for 13.4, 14.3, 15.89 and 18.1grain "tunes." I've not been so happy with output and consistency when trying to use the same reg pressure for anything 20grain + in .22. Ie. the gun needs a higher reg pressure for the heavier .22 stuff than it does for the 13.4-18.1grain weight range. And THAT is where an externally adjustable regulator (like found on guns that ARE NOT Veterans) becomes so convenient.

Maverick fits the bill, but I already have one in 25 caliber. For my next gun I'm looking for something a little less complex and more "simple". My Maverick is great, but it has it's "issues" at times. A big issue is that I have to be very careful when transporting the gun, very easy to have the POI shift. I added a tensioner to help with the problem, but I still experience it at times. Can't overcome the FX barrel design, just not super rigid. Accurate yes, and adaptable, but not very stiff. That is why the Taipan Veteran is at the top of my list.

Is the Prophet less prone to POI shift compared to the FX guns? I know you can swap the barrel etc, so that makes me a bit nervous.

The RTI guns are built as truck guns —
to drive... to a competition....! 😆

Tough — AND precise.

The barrel is a barrel — not a straw....


I was on a similar quest as the OP:
The group of guns that offer external adjustability of REG and HST is very small — and it seems every path leads back to FX. —— But I needed adjustability AND toughness. RTI delivers both. And with only a third of the amount of o-rings..... 😉
