HPA or Co2?...........

"You know what? You want to test your recoil backspin theory? Use a VM68. If anything is going to give results, it will be that."

I've been wanting to say that.........

My view on that: yes. Recoil might put a slight spin on the ball that might drag it down. But that just means the barrel lifted up, too. So you're also shooting higher, effectively. Problem solved.

E

why?

guys, seriously, read the thread. we dealt with all these issues already. i already brought up the VM68 to jack ... read the damn thread

Read the thread...did....

Regarding the VM68... it's also a bit heavier than an Ego, meaning more inertial mass, and a "slower" recoil. Might make a difference...

Barrel, suppose porting has some affect. It's a variable, and we're trying to eliminate variables.

Suppose the kick is 5*, but the spin reduces range by 30 feet, it might not be an 'even set". Also, supposing there's underbrush or soemthing, a flatter or steeper trajectory has a different "line" through the "lane". And really, range isn't the issue, it's the pursuit of knowledge. If I wanted range, I'd stick to real guns.

...and isn't the Magnus Effect just a very form-specific Bernoulli effect, in that it still moves towards the region of low pressure, as caused by high velocity?

Sure, you can boil it down to that, but Magnus effect is the correct term in this case.

Really, all things being equal, one gun should shoot just as far as the next.

Hasn't anybody considered that the reason for the "definite" downward arc seen in one marker and not the next is due to bore match? Consider this, how many of you guys have been complaining about the small paint? If paint is undersized, I would imagine that it would have a tendency to roll along the bottom of the barrel. (Producing forward spin and an inverted Magnus Effect) Likewise I could also see "unbalanced" detent systems possibly causing some weird spin issues.

My personal opinion is that paintball guns have neglible "recoil", and markers that are renowned for "kick" infact do not recoil at all....Recoil as applied to firearms refers to the motion of the firearm in reaction to the bullets (Newton's 3rd law) "Kick/Recoil" as applied to the VM68 or the 68 Special refers to the force of the considerable hammer/bolt assembly hitting the valve pin. If anything that causes the marker to pitch forward slightly. You're not going to feel the recoil from firing a 3 gram (46 grain) projectile at 300 fps when you can just barely feel the recoil of a 22 LR (40 grain bullet at 1260 fps) By the recoil argument logic, real firearms should all be wildly inaccurate. In real guns, taller stock profiles means a little less felt recoil, accuracy issues cause by recoil are a shooter issue (he's flinching).

Ugh....these threads on PBN just give me a headache after a while

It's basically just marketing hype. When it comes to range shooting, I can pretty much drive tacks with any of my guns to about 20 yards. Now when I say "drive tacks" I mean that I can put the shots into about a 6 inch circle. When I'm on the field everything is up in the air. If you don't see me, and I take the time to really line up the shot, I will hit you from any range out to about 30 yards; assuming that I didn't leave the paint in the pod for 3 months and now have a PGP full of eggs that fly in random directions after about 20 feet. Most of the time when I play I figure that I have an effective range of about 30 feet. Past that, pucker factor and weird paint ballistics (because of the variables in paint manufacturing) kill aim. It always cracks me up when we play "Alamo" at the field I frequent, and the shooting starts when the aggressors are about 40 yards from the fort.

Catchya on the Flip Side.....

Okay, I finally looked at the pbn thread.

I really wish I didn't.

Basically the only thing in there that didn't make me want to murder someone was Doc's response to Sean.
