Will shooting lower velocities help a gun be "more accurate"? The boys over in the uk seem to be pretty accurate at sub 12ft.. That makes me wonder will the over all function/recoil/movement through out the shot cycle help the gun (pcp) be more repeatable/forgiving etc.? im not talking pellet stability in flight on talking before the pellet leaves the barrel and just before the sear on the trigger breaks.. Im thinking of tuning my gun down to 700-750 fps.. What would the benefits other than shot count be for shooting that low? any info helps

Cal: .177 pellets: 9.1 Norma's

What the boys in the UK do with their airguns simply proves the point of coming to airguns in the first place. They git a lot done with sub 12 FPE. Here in America we are free to chase the ridiculous… Pariticularly since we are still allowed to🙄 own powder burners… God Bless America…

Newtons 3rd law of physics ( That of of equal & opposite reaction ) is the primary thing in play here. Even tho pellet is 9.1 grains it's acceleration from a stand still to what ever speed it max's out to at exit the reaction / recoil it imparts to the rifle will vary with the speed. The rifle has mass and that alone absorbs recoil energy, so ... if power/speed is low the reactive forces of the pellet being brought up to speed will happen more subtle and rifle motion will be less.
But not all lunches are free either ... as in the slower a pellet travels down length of barrel the more time any reactive recoil of the shot cycle might shift POA position before exiting muzzle ... Damn !!

A faster setting May or May Not get pellet free of barrel faster and stated reactive recoil might lag it enough to be more accurate ... Huh ?

MUZZLE BLAST that reacts against the ambient air creates POST projectile EXIT RECOIL and outside of another conversation ( Turbulence ) does not effect accuracy as the projectile is out & on its way when this secondary recoil event happens.

Just a loose bit of FYI ... nothing concrete in all honesty.

Thats the kind of info im looking for! obviously Newtons laws, good guy and all but yes there is diminishing returns. Just kind of like when you can HEAR a rifle and its tuned good, it sounds like its functioning happily. Now im going for over all FEEL of the whole shot process. 1 because it makes shooting much nicer and 2 if there is improved accuracy and more shots, im on board.. it good to have a variety of guns with a variety of tunes for a variety of things.. this one is gonna be the 25 yard beak spinner lol

Interesting stuff!

The people at Feinwerkbau thought enough about Newtons 3rd Law that they designed an adjustable little gizmo to offset the pellet acceleration for their Model 603 10 meter SSP target rifle.

The firing cycle on the 603 is dead calm so I presume it works but I've never never had the chance to compare to the 601/602 models without the compensator.

Cheers!

STEYR LG-100 and LG-110 PCP's did something similar as well.

then there's also the difference between a PCP/CO2 and spring guns.. with spring guns you got a lot more going on, and to my understanding on the spring guns pretty much all the going on stuff is before the pellet leaves the barrel..note, I'm not sure if the pellet leaves the barrel before or right around the time the piston stops moving but I think 🤔 it's stopped before the pellet leaves..
also this is why lower power spring gun is easier to handle if it is not a magnum..
I can't say that I noticed a PCP being more accurate at any given speed, assuming you keep it around 950 and don't break the sound barrier..
on my airforce Condor I can't tell any difference in accuracy in various power levels as long as it's subsonic.. course you'll have a more rainbow trajectory the slower it's shooting at long distance.
just my worthless 2 cents..

Here's my 2 cents. If you practice & master your gun's characteristics at ANY SETTINGS it makes one an all around better shooter. You COULD tune for less recoil & reaction but, imho, if you condition your body to shoot well no matter what recoil or fps, that's more desirable & will benefit one's technique more in the long run. Of course tuning for gun's efficient functionality is important but tuning JUST to reduce recoil for shooter behind the trigger doesn't mean that's most efficient for the gun. Does that make sense to anyone other than me?

If is a sub conversation to OP's inquire ... Operational parameters and optimizing ones self to make the best of how an air guns shoots is indeed part of accuracy & consistency conversations :unsure: (y)

Then there is also the question of what the gun in question likes or does not like - I have a .22 Sidewinder that I would love to get to shoot well at 800 fps and under, but there is no ammo that it likes at the lower speeds. It only shoots well above 875 fps, and even better from 900-950 fps. I want it at lower power as the gun is a little harsh at higher power, and it would be so much more pleasant to shoot at the lower speeds - but the accuracy stinks there . . .

The physics and forces may be predictable, but you won't know this one until you try it.

Motorhead explained it well. What others say is also true.This whole subject is fascinating; when I think of which is a better way to achieve what you are trying to achieve,do not leave yourself out of the picture. Also, are you able to hold the rifle? Yes, there are certain FPS that pellets,ammo, rifles, etc. like.
It is not just air rifles; most things have a "sweet spot."Is it a "Gasalt thing"I think it is, The whole is greater than the sum of the parts. As you see, an easy answer can be complicated. :ROFLMAO:
