Tuning Taipan Compact .25 - lead free - sub 15 fpe

[Dairyboy]

Did it come at 13fpe, or did you have to tune it? Can an average Joe adjust the reg and hammer spring on the Vixen, or does it take involved airgun surgery?

Thanks,

My .177 came tuned there out of the box. I have the short/standard version. But is very easy to adjust if need be.

An overview by Sub12 very recently

I know nothing of Taipans but can chime in about the lead-free .25 pellets. There are two that I know of that are good, the H&N Baracuda Greens in 20 grain and the Predator GTOs in 16.5 grain, and both can be accurate out of the right gun or right tune. From a rest they will shoot an inch at 50 yards out of my Seneca Aspen and Airforce Condor. The GTOs will do that down to 13 ft#, so maybe they are more forgiving of low velocity, but of course it always depends on one's particular gun. Of note they can be shot backwards at close range and will expand like a hollow point.

The third pellet I know of is the Skenko Black Max 32 grain, which is some kind of steel head with a plastic skirt/sabot, which I have found inaccurate in every .25 gun I've tried (Hatsans, Aspen, Airforce). Oh, and Zan makes an unleaded slug in .25 but I haven't tried them yet.

In .22 there are more like half a dozen options, and in .177 there are a dozen or so.

I have a vixen in .177 that I bounce around from 860 to 580ish fps with just the hammer spring adjustment. I know this isn't the best way to get the very most out of a pcp but it's working well and I get consistent results throughout that range. The last 10 shots over a chronograph using JTS 10.4gr averaged
FPS 591.2
SD 1.03
V 1.06
ES 3
FT,LBS 8.05
and 1.375 bar per shot averaged from 80 shot.

Solid suggestion for a barn gun.
