Default Pros and Cons of .50

CREDIT GOES TO GEEKGOD FROM PBN

I did not see a thread pertaining to this subject in the ASM forum and seeing as i see people with ASM to be a lot more mature and educated than the rest of the pbnation population i felt like this would be a good place for this topic to be discused and talked about. My first two posts are as unbiased as i can get them, and the 3rd post is my personal feeling on the matter and what i have gained from the reading i have done

Pros and Cons of .50

As not only a player but also as someone who works in the industry I took it upon myself to write up a pros and cons list to hopefully start good educated discussion. I would like this thread to not create flaming but smart educated discussion.

First off lets knock out some quick math witch I will reference quite a few times threw my discussion.
To understand the size difference we must first know the difference in volume of each size paintball.
Volume of a sphere= 4/3*Pie*radius^3

V of .68=0.16463621020893518
V of .50= 0.06544984694979167

With those 2 numbers we can figure out that a .50 takes up 60.246% less space than a .68 paintball. (** I know you never thought you would use algebra and geometry again but I guess my math teacher was right:P )


Pros
1. More shots per fill. With a 60% smaller paintball it will take over half the amount of energy it took to speed a .68 ball to the same speed (300fps) meaning that each shot takes less air from your tank.

2. Smaller gun With the smaller ball taking less energy to propel the ball down the barrel and eventually reaching 300fps means a few things. Gun its self can get smaller. with the projectile becoming smaller the valve chamber on a gun can become smaller while also the breach and bolt of the gun can be drastically reduced creating a smaller lighter gun.

3. Smaller Tanks With shots per fill increasing you can pick two different options. you can carry the same size tank and shoot that much more paint per game. or the actual size and weight of the tanks will decrease allowing you to shoot the same amount of paint you do now only your profile and weight are reduced that much more.

4. Smaller Loaders With a smaller ball the amount of space needed to carry 180-200 rounds will be much smaller. again further reducing your over all profile/ weight of your gun. On top of that with a smaller hopper and feed neck your field of vision will be increased.

5. Smaller Packs/Pods With the .50 ball taking up less space caring 2000 rounds on your back would be something that is quite easy to do. If the ball takes up less than half the space of a .68 ball that means instead of you fitting 140 rounds in each pod you can fit close to 350 rounds in the same space. So a case on your back will technically speaking only take up the same space as 5.17 pods! Again adding to the reduced overall weight of your gear.

6. Reduced Price With the balls being 60% smaller you can imagine 2000 rounds costing less than half of what it does now! the price will be reduced in 3 ways. 1. Smaller ball= less material used to make the ball. 2. With a smaller ball the box that holds 2000 rounds will take less cardboard and less ink (to print the pretty pictures on the boxes) 3. With smaller boxes more cases of paint can be fit onto 1 shipping skid reducing the price of shipping costs per ball.

7. Less pain Using the equation Mass*Velocity= Force. If the .50 ball weights half that of a .68 ball then essentially it will have half the force. because in this equation velocity is the constant (assuming we keep the fps to 300 fps) and the mass of the actual ball is the variable that we are changing and force is what is effected in the end. (**If the .50 ball takes up over half the space of a .68 ball I am going to make the assumption that a .50 ball weights over half the weight of a .68 ball**) The question I have about this statement though is with a smaller surface area the force will be applied on a smaller portion of skin which would complete negate this Con but I do not have a math equation to prove or disprove this point. Nor a .50 ball to shoot at my own leg so we shall see what the outcome is. *if I did have one I would

8. Shorter Bolt Movement With the ball being much smaller this will allow for bolts to travel a shorter distance to clear the breach to allow the next ball to fall into place. What this does is 3 things. 1. Much higher rates of fire could be achieved due to the bolt having to travel less distance. 2. The bolt and rammer (if we're talking about a poppet gun) both can be shorter reducing the weight of the reciprocating mass decreasing the amount of kick you will get form you gun. And lastly with the bolt and rammer both traveling shorter distances the guns them self will again become shorter and smaller adding to the advantage of having a smaller/lighter gun.

9. Hoppers Feed Rate will Increase The feed rate of hoppers will increase without any significant changes. Dye is already (and supposedly done with) a drop in "upgrade" for .50 paint. If we look at a rotor you can fit (I'm taking a guess cause I don't have a rotor in front of me) 10 balls in the catch cup (where the red "Shark Tail" is) well if you decrease the size of the ball and allow 13 balls in that catch cup and the speed of the "shark tail" moving is constant than if have just increased the feed rate of the rotor from 20bps to 26 bps.
Also to go along with the hopper functioning faster if we look specifically at the breach of the gun its self, due to the ball and breach being smaller after a shot has occurred; as the bolt comes back to allow for another ball to fall into the breach since the ball its self is smaller it has a shorter distance to fall into place again increasing the feed rate for loaders

Before I explain some of the cons I would like to touch on a small amount of physics first. With the idea of Mass*Velocity=Force if the mass is lowered and the velocity is kept constant then force is lowered. If forced is lower than distance traveled by the projectile will be shorter (in a vacuum). But we are in the real world and we are not in a vacuum so we have this thing called "drag" or "friction". Friction is applied on the ball by the air the ball is traveling through. There for if the ball is smaller than less drag is applied to the ball meaning it has less resistance while traveling through the air. Whether or not the friction co-efficient is enough to outweigh the force and momentum of the ball is something I would need exact measurement and weights for each ball for. (if you happen to have a .50 ball PLEASE get some digital calipers give me a exact measurement and weight of the ball it would help allot)

Example: pick up a full (23oz) Arizona tea can and throw it as hard as you can. Now take a empty one and throw it as far as you can. The full can will travel a farther distance due to it having more force with the same amount of drag. But now if you took a full (12oz) RedBull can and throw it. Witch went further the full Arizona or the Redbull? Without knowing weights and exact sizes of the full and empty cans we can't know unless we test it.
