Observations About My PCPs

Not interested in trashing any manufacturer but here's what I have experienced and am wondering if your experience is similar. I have a FX Dreamline Tactical in .22, and a Leyla 2 .25, and a Taipan veteran shorty in 25. At targets in my field I practice hitting those targets from a bench rest and tripods. I start off in the morining and even though my FX was almost a tack driver when I practiced last afternoon, I now need about a full magazine to get it back on the tack. I even bought and installed a barrell band and I think that has helped. This point of impact shift isn't satisfactory if you are pesting.

On the other hand, the Leyla 2 needs minor adjusting between sessions if any and would get the pesting target probably without too much problem. The solid performer is the Taipan Veteran. I can throw it in the back seat, lean it against the wall, anything except 'baby' it. I can count on it being totally on target at 50, dead center the first shot. I think the barrell length on the Leyla and the Taipan are really near the same length. They are short!! But they are the most consistent performers.

I've had a Wildcat II and now the Dreamline behave the same. Not repeatedly accurate when you first start shooting but after a mag or two they settle down and hold their zero. However the next day I will need to readjust the zero on both FXs. The FX is such a wonderful product, maybe the Cadillac of PCPs, but mine won't hold zero overnight.


 
Dryfire pop off a few rounds to settle it before doing any serious shooting. This phenomenon is normal for many FXs not everyone's gun has this issue though it can happen at any time so just do the pop off ritual simple. Even professional tuners and serious target shooters will tell you to do this. YO!

you mean when regulator is creeping? one shot is enough 



but i am sure poi shifts are because barrel is not fixed with the barrel band. all the manufacturers use them. even with the full thick massive barrels. and here in FX we have thin liner system which is too much flexible

My primary rig is a Brocock Bantam Sniper HR with a Athlon Helos atop it replaced my Compatto with a Aztec Emerald atop. Which was relegated to backup duty and spends a lot of time in the safe. The Compatto is sighted in at 40 yards. This thread inspired me to pull it out and see if held its last zero. It definitely does, it put all 5 shots into a dime size group at the POA. So as a reward I took it down to the dairy where we made six kills from 40 to 60 yards with a 7 to 11 mph wind. 3 starlings and 3 pigeons. Both of my Brococks hold POI/POA from day to day. At most I might have to adjust for windage depending on the wind conditions for any given day.

I have only noticed it on my Wildcat II and the Dreamline. Had a T-12 Whisper, a Crown, and an Impact. I was almost a newbie then but didn't notice POI changes.

To answer a question farther up, I do have to readjust the turrets to get it back on zero. I did put a barrel band on it and have only had it on their one day. Gonna go out in a bit, fire some 'blanks' like suggested and hold my breath that POI is the same as it was yesterday.

Comforting in one sense that I am no alone in this experience.

Like Yo pointed out a regulator that is working properly but set at a lower barPSI will need to have some shots dry fired before shooting any ammo. If your regulator is at the upper end of its pressure then probably not as Ernest Rowe has discovered. It could be a barrel shift too. You could try bumping your regulator pressure up and see if this holds true for your FX over night.

Here are the musings of an old fart, take it for what it's worth. Whether air rifle, car, or lawn mower, you can make things complicated, or you can make things simple. In the air rifle world, if you want consistent accuracy and mechanical dependability, you need a good barrel (a real barrel, not a sleeve and liner), and a simple, robust platform. In my experience, some of those are, Taipan Veteran, RAW, and early FX rifles (Royale). I'll also include Steyr and Anschutz, they're not especially simple (German and Austrian, after all), but they behave like they are simple. Weihrauch is probably in there too. I give up, I don't know how the Germans make stuff so complicated that work so well. My rule of thumb, if it has any adjustments beyond trigger and hammer spring tension, I'll let someone else play with it. May be a weakness on my part, but it's my money.

I might have to make 3 or 4 clicks on occasion but it never wanders beyond that. I always thought it was temp, atmosphere or weather conditions but my 3 FX guns haven’t had any issues except for a regulator issue (I think) when I first got the WC. I tore the reg down and cleaned it up, lubed and reinstalled. I haven’t noticed any thing else since then. I have a Wildcat, Streamline and Royale 400.

🔶 So, could you help a slightly confused not-yet-FX shooter to get this straight?: 🤔



Many FX long rifles and bullpups — when shot after a pause of a dozen or more hours — give several shots that hit offset from where the gun was zeroed.



(1) Either because the barrel got "bent" the wrong way when stored and not used. (Is this the same barrel bump sensitivity that kept me from ever buying a Gauntlet?) 



(2) Or because the regulator needes some kind of "warm up."



Thanks for enlightening me here — eventually I might stumble over a pot of gold and buy another PCP — and some of the FX's look pretty sweet.

However, barrel bump sensitivity and regulator warm up routines are total deal breakers — my backpack does bump the guns, and my pesting shots are often super-short-notice shots (NO dry-fire-jump-start-the-regulator). 😄
