It depends in firearms what powder is used .slow powder long barrel .fast powder short . In springers 1:27 22 cm is most the point where more lenght does not much .a short barrel is more accurat .because its stiffer .and the pellet is leaving sooner the barrel
It absolutely matters with powder burning guns. But I don't think there's much difference in air rifles. 97K and prosport barrels are only around 11.0" and they make great velocity. I don't have any experience with PCP's, so I know nothing about them.
Great stuff I understand that with the lack of combustion it won't make a difference with air rifles,but knowing the sweet spot of improved accuracy over friction drag would be interesting 👍
Nick I would like you to take this a little further specifically in search of the optimal barrel length for sub 12 fpe air rifles in .22 and .177. I am assuming there is a perfect length of barrel for both calibres where drag is least prevalent and power is effected least yet accuracy is not compromised. Carbines are super popular these days but are they optimal?
A longer barrel will give greater velocity, this has been tested with UK spring rifles in the past (by Gerald Cardew) but it was found that the pellet's acceleration occurs mostly within the first 10" (25cm) so carbine style springers lose very little available velocity for having a shortened barrel. A longer barrel is only a little bit more efficient at utilising the expanding air. But a longer barrel does add some weight to the front of the rifle, may make the shot cycle feel smoother, helps aiming with traditional iron sights (sight radius is increased) and it acts as a longer cocking lever.
Thanks Nick, I'd not known the actual increase, I knew there was a good amount of power gained, but the figures speak for themselves . In police circles , 38 special is not regarded as a very good man stopper, I guess when the perp is drugged out of his mind on some of the stuff today, not a lot of hand guns will bring him down, unless its an instant fatal shot , so , clearly a police 38 special in 5 inches or longer is a good gun / load .
Extra length up to a point, makes extra power in pcp, but imo when barrels go beyond 21inch then form has to be factored in to you shooting.👍
I learned this lesson after swapping barrels on my ld rat catcher. The 24'' barrels made it past 15flbs so I settled on an 18'' to keep it legal

My AS 2250 crosman went up with the 2260 rabbit stopper barrel on it . a bit spindly but made it a good short range lightweight Rabbit rifle.
you make the best videos thank you👍
Im curious how the different rifling in the barrels effected the results
ooh, i like that gambler spud gun on your table.

Carbine barrels are optimal for springers.
I'm tuning two break barrels a xisco xs 25 and a Gamo big cat 1000. I will be cutting the barrels to 13 inches and attaching silencers.
This is interesting stuff!
And the airguns??

Would love to see more of the Marlin at the range 👍👍especially if you have any empty xmas beer kegs.😀
Very interesting.
Nice vid nick xden

Interesting
Barrel length makes no difference at all.
He literally just proved it does in the video 🙄
Makes no difference at all! To what🤷♀️
@@davep6286 you clearly didn’t watch the video
@@davep6286 makes no difference to accuracy.
That is what she tells you, but she is just being kind👍
