N/A Does velocity effect rifle sensitivity when shooting?

[LancasterAirgunner24]

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…

To keep with the spirit of the OP my sub 725 FPS Atomics, simply kick ass out to 50 yards.. many pest would attest if they could…

What do you mean coming to airguns in the first place? and i know, being able to shoot however fast i want is great but i know about advertising/trying to sell products etc lol

Ive shot slower speeds before and it just feels so much more effortless and things arent so erratic despite a good tune. I can alot more about accuracy than shooting hot. Thats what the AT-44 is for, slinging 10.5g at 920.. chocked barrel, build quality just makes it shoot nice for obviously shooting hot for a 177.

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.

Velocity does affect accuracy as well as a myriad of other variables too many to mention.

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..
