There are no 45 caliber paintballs. If there were, you still could not use them in a 50 caliber, due to the barrel being larger and that you would have 1 and 1/4 paintballs in the chamber at a time, which would chop every time.
No. only .50 caliber paintballs.
yes, they require 50 caliber paintballs, the industry standard is 68 caliber
In U.K, the paintball fields set them at 270 FPS, but when you buy the gun it should be around 300 FPS, you can buy chrongraphs for $10-20 to test the FPS,
The highest caliber machine gun in standard use is the .50 Cal. Gatling guns are used in 20mm caliber. XXXXXXXXX Russia and China use a heavy machine gun larger than the .50 cal BMG- it is the Vladmirov KDV (for the Russians), in caliber 14.5mm x 115.
A 50 caliber gun, or more properly, a .50 caliber gun is a firearm having an internal bore diameter of 1/2 or .50 of an inch.
It depends on what type of marker it is, and what size of the paint you are using. Note: these numbers are average for 68-caliber paintballs (the most widely used size of paintballs). Your actual number can be higher if you use a smaller size of paintball (e.g. 50-caliber paintballs) If it's a hopper-fed, it could be somewhere from 100 to 200 on the average. If it's fed by a tube or some form of limited-paint format (like a paintball "magazine"), it could go from 10 to 20 paintballs or so.
