Do you really want ‘powerful’?
Or more consistent etc?
Paintball is limited by legislation, precident and rules.
Legislation covers energy - 12ft pounds for air rifles, 6ft pounds for air pistols
The 12ft pounds with an average 0.68” paintball is a bit over 300fps velocity
There’s also case law dating back to when paintball was Co2 only, and that went for something a little over 300fps velocity as the maximum.
It is generally accepted that 300fps is the maximum permitted
Tournaments tend to set the limit at 300fps
Recreational such as walkons, scenarios etc tend to go for 280fps
Indoor games may set a lower veleocity
Rentals are likely to go for 280fps but might be a little lower - it depends on the site, and they may drop due to many of them using co2 and the velocity could vary during the day depending on atmospheric conditions (warm, cold etc)
First strike shaped projectiles have been officially tested with no true energy difference so can be shot at the same velocity. However they retain their energy for longer. Depending on site they may be fired up to 280fps, but if a player uses a mix of hopper and magazine then they would have to chrono so that neither exceeds the maximum allowed
Other calibers such as .43” and .50” can theoretically be fired at a higher velocity due to lower mass meaning a lower energy. These sizes have been used in some pistols
Certain magfed events might allow a higher velocity for .43 and .50, or they may stick to 280 as they would most likely be used for close range anyway
.50” proved popular as ‘low impact’ for younger kids groups ... such as spaltmaster .50s (not the original paintball spaltmaster .68 pistol) and also for rental sites with ‘normal’ paintball guns at .50, either using only .50 instead of .68 or as another option for groups. They may stick to something like 280fps to gain the benefit of lower impact for kids and other rentals.
It might seem that you want the most powerful / highest velocity, to compete with others, but if you fine tune over a range then it is often found that barrel consistency has the most influence. A number of barrels can be adjusted with size inserts.
The optimum range / accuracy consistency can often be achieved by barrel selection and a slight drop in velocity.
There is ‘perceived range’. When you shoot you can only see if someone is hit or the ball splats against something.
Whereas you can see every ball that bounces around near you — it might seem that the opposition have better range, but the balls could be arriving at their furthest reach with no energy.
The best place to shoot is on site, but some people do want to shoot at home or on private land. This may or may not be legal depending on the exact circumstances, and even if legal could be the subject of complaints and ASBOs.
If legal and without complaints, as long as it’s conducted safely in a controlled environment then you aren’t bound by site rules but remain bound by legal limits.
