These are two separate questions, but yes, barrel lenght and propellant affect the distance and accuracy of paintballs.
No. Only if you are VERY far away, the paintball may not break at all.
Almost all barrels are made with a slight overbore. Too much overboring will cause the paintball to lack power.
It is completely dependent on you paint quality, how it matches the barrel and the consistency of your propellant, the gun itself may only affect %10 or less of accuracy.
Height does not really affect the accuracy of your basketball throwing. However, tall people tend to underestimate the distance to the net and small people tend to overestimate the distance to the net.
Its going to affect accuracy a bit, and air efficiency a whole lot.
Using a 40 cal pepperball in a 50 cal paintball gun is not recommended as it can cause damage to the gun and affect its accuracy. It's important to always match the caliber of the ammunition with the gun to ensure safe and effective shooting.
if a target is close to you then it will be easier to hit. but it also depends what kind of target . for example if your shooting a apple then it will be difficult to hit it but if it is a paper box then it will be much easier.
Chlamydia does not affect the accuracy of a chlamydia test.
Trichomoniasis does not affect the accuracy of a pregnancy test.
No, HPV doesn't affect the accuracy of chlamydia tests.
Pseudorandom numbers can affect the accuracy of a simulation by accidentally causes pattens that could be missed by the system. This could skew the accuracy.
they are more lickly to chop when they are hotter they'll break inside the gun and that isn't very good when your in the middle of the battlefield. and if it does happen you have to clean the barrel with a squeegie or a cloth or something.
