Is the .25 cal LW barrel accurate in just 12 Inches length?
Posted: Thu Aug 15, 2013 12:09 am
Every once in a while I get this question, “Are shorter barrels accurate out of a PCP Airgun”
I have always believed and said, yes they are mighty accurate at shorter lengths and
would perform the same competing with longer barrels or even better due to lesser barrel harmonics.
Kindly note we are not debating power here as most of us know that PCP Airguns
shoot at higher velocities as the length increases thereby increase in power.
Imp Note: This conclusion is only pertaining to PCP Airguns and as it comes to Springer’s or firearms, the finding would differ.
So for performing our tests I have taken an Airforce Talon frame with a 12 Inches LW barrel in .25 cal.
Couple of modifications have been done to upgrade the power.
Modifications were done to upgrade the power and not to improve accuracy.
They do shoot well out of the box but these are the wild pcp’s and do need to be tamed.
Now that’s the price you pay for a wild pcp, over a tamed FX which comes with all goodies ready to go.
I could point out the PRO’s and CONS in both but that would be a different topic altogether.
Let’s stick to the subject here.
This one in 12inches barrel length shoots at higher power than the stock FX royale 500 in .25 cal.
I have the numbers but don’t want to share them for all good reasons.
Appreciate if you folks would co-operate here and for those discussions, kindly stick to PM’S.
However I did mention the power at which it performs, if you read between the above lines.
All these power tests have been done over a chronograph.
Best I have indoors is 10 meters, so that’s the best of what I could make for now.
See the results for yourself for a 5 shot group.
The Original Video had to be edited as the size was 596MB.
I cropped off the part in between and the resultant video goes like this.

Here you go with some measurements of the groups.
What better than comparing the groups to one of our new rupee coin?
Kindly note these domed or semi domed pellet do not punch accurate holes into paper like the wad cutters do.
So these groups seem real tight to me, what we call “Hole-n-Hole”
I have Also attached a video for the Sound difference with a Tony Shroud and without a Tony Shroud.
The sound test was done in a closed 10X10 sq. feet room which is injustice to the real world sound report.
I do not have a decibel meter for the exact sound reading and so that’s the best for now.
It’s much more silent in the open with the shroud.
Note:- Do remember to adjust your speaker Volume.

Length Factor:
As you can see below the whole length with Tony shroud is 37 Inches in length.
And you have a quieter, shorter, powerful pcp than a FX Royale 500.
I keep talking about the FX royale as that’s another pcp I have extensively worked upon.
The length of the setup without the Tony Shroud is 28 Inches in Length.
If sound doesn’t matter to you.
Ordinarily I personally don’t think there is another pcp package out there this short and powerful.
Until Next time....Best I could Chime...
