i have a power feed right minimag so the nubbin is located on the bottom of the barrel i thought it could be suspect of topspin(no not enough to have the ball fall 10 feet in frount of you thats like saying the flatline after 10 feet goes straight up), but enough topspin to cause a noticible difference in distance. we both have poor paint barrel matches with medium bore(the ball kinda slides a little through when placed in the mussle on both markers) also how could paint to barrel match affect distance on 2 paintballs going the same velocity with the same mass? i dont think paint to barel match effects distance but it does effect efficiency so the only thing i can think of is a mild topspin to affect distance
mag range(not what you think)

The paint to barrel match does matter because as the ball exits the barrel, the amount of air passing over the surface of the ball will be different. Thus, if the match is poor, air passing over one side of the ball and not the other could cause a little bit of spin on the ball as it exits the barrel and hits the outside air, causing god knows what sort of spin. For a better paint to barrel match, the airflow around the ball upon exit will be more consistent around the ball, and the ball will be less likely to fly all over the place. That's what porting does.
As for your nubbin, that's not your problem, again, unless your barrel to paint match is crappy or you have a huge nubbin. I'd go as far as to say if you have a good match, the paintball won't even complete a quarter of a rotation in any given direction before it exits the barrel, simply because for the ball to spin, there must be a difference in pressure around the ball, and there isn't enough room for that to happen. But, if your barrel is much bigger than your paint, the ball could tumble a bit inside it, but again, not a whole lot, and have a bit of a spin on the way out.
Also, bigger paint won't fly as far. So, if you're using BE paint (please God no) and your friend is using marbs, you'll lose the distance contest nearly everytime. There is more surface area for bigger paint and therefore more air resistance.
My friend brought up a point in the closed-bolt vs open bolt I hadn't ever thought of, so, I thought I'd mention it. By the way, I haven't read a whole lot of previous debates so if i'm repeating stuff you know, sorry. My friend brought up the idea of slight ball deformation. Closed bolt guns run off low-pressure, so, technically, the initial pressure on the ball is less than that of an open bolt, just the time exposed to the pressure is a bit longer. I don't really believe that this would have any sort of outstanding effect on the ball while in the barrel, but it could after exiting. The aerodynamics of the ball would be a little different and the ball could tumble.
So, you and your friend get good barrels, good paint, good tanks, shoot about 15 times and average your distances. If the cocker still shoots farther, i'll give you a shiny nickel.
Oh, and by the way, Flymonkey53 Distance = velocity x time, not mass. Momentum = velocity x mass.

Thank you for that last post. We are both using the same paint and it is definitely not brass eagle(we know better). Im sure if i get a good aftermarket barrel with a proper paint to barrel match my problem will be fixed. I just thought i would blame it on the nubbin. Thanks. And for the closed bolt vs open i dont think it would make a difference. Im pretty sure i wont be recieving that nicle but it was a nice offer anyway.

if the ball starts on the nubbin, it wont creat the backspin like you think. a zbody start behind, and the ball rolls into the skidplate, then gets backspin. the skid plate is wide and actually CATCHES the ball. the nubbin is tiny, thin, and actually will give a little before the ball has a chance the deform or spin. so highly doubtful your nubbin is killing it. your barrels may be different diameteres, medium barrel to small paint isnt great, but you may be a tad larger inside the barrel. that will kill effeciency, accuracy, and distance. you'd be suprised what can happen inside that barrel. bouncing and everything else. my last advice? just keep beating his cocker with your mag, proving once again, mags rule the day. hehehe have fun."Mad Painter"

The range on your minimag is fine. The autococker is simply more accurate and has better range. Some dont believe it, but after you get outranged by one you will have to admit it. Although the autococker has better range and accuracy, the mag has its definite advantages.

I DONT want to piss anyone off but answer me this.
Last time I played there was a guy with a minimag, i was using my friends 99 cocker. Guy in a bunker probably 200 feet off maybe more/less dont remember. I asked if he had a good shot, he shot and the ball fell short every time. I steped up and nailed the guy within 3-4 shots. If the cocker does not shoot better, AT ALL, as everyone so far has stated, Then how come it proves itself at the field, Don't care what anyone says on the Boards.
It's all preferance though, I simply prefer the cocker, however I am still building a mag, to switch off depending if I play front or back.Polished Standard feed body

Many variables besides the gun. Velocity. Type of paint. Paint-to-barrel match. Angle being shot. Perception.
The only way you could get more range from a particular gun w/o spin is if the gun could magically make it accelerate after it left the barrel... hence the AO elf brigade. 300ft/sec is 300ft/sec.
My theory is that the rear of the cocker, including the back block, must be weighted to make every cocker user tilt the gun higher up or something.

Well my paint was way too small for my barrel,it was rolluing out the end,dont know what his was. dont know about velocity- less than 300 though
I know it is the same coming out of the barrel but the chrono takes a measure of the velocity at that second which finds the average velocity. Thwe thing is, velocity can accelerate, which IS possible, it measures only at that point though. Now if we could graph it using a motion detector which measures the velocity at any given point on the graph, in other words finding the limits or derivative.

Way too complicated for the stupid arguments that come from paintball guns.
SO I am giving up, I really whish somone would write an in depth article about his so we could end the madness! AHHHH!

just what are these advantages. I recently bought a minimag and have only used it once. I love it, but I haven't quite gotten to know it yet. Also is there anyway to get them to perform well in cold weather? I just bought a reg (vigilante). What else would be good?Go tell your mom.

It cannot continue to accelerate unless a force is applied. Newton would agree.
Once out the barrel, or past the porting, there is nothing pushing the ball. The ball also leaves the barrel well before the air escapes, so there is no cushion of air or anything that could help push it.
Limits? Derivatives? Bah. We don't need those.
Testing the ball like you mentioned... already done. What's been found with high speed video: Acceleration out the barrel - negligible. Ball leaves barrel well before gas does... like I mentioned.

As an owner of just about every high end gun on the market (cept excal and matrix, soon to have matrix) I can safely say that no gun shoots further than another. The only difference I have ever noticed is the way you have to aim different guns, with cockers and angels I usually just aim strait down the rail, with shockers I've noticed I usually have to aim a little high cause something just doesn't seem to line up, and the only mag I've ever owned my e-mag (best gun ever!) seems to shoot high when I have the site rail on, I had to aim at peoples feet for a while after getting it just to hit there chest (in a kneeling position). I solved that problem by taking off the site rail and siting down the body.Comment

i appologise to the forum i didnt want this to be a range debate. If the same paint is coming out of the same barrel at the same velocity the range is the same(discluding spin). THe bolt configuration doesnt matter.-Minimag Body HR
