Pipes as you are the UK voice of .50 cal
Am I right in saying that the accuracy of the .50 cal partially comes from the fact that it is fired at a higher fps compared to .68 cal?
The accuracy of any paintball comes from the spec it's manufactured to not from the velocity it is fired.
I had better declare an interest here inasmuch as I am working with Richmond as a consultant, nothing major, it's just helping out every now and then with this 50 cal project.
The .50 calibre ball is fired at exactly the same velocity as .68, the fact it has less kinetic energy (by virtue of a reduced mass) is a bonus when it comes to legislation in certain countries.
The accuracy however is an emergent property of consistency of fill and quality of roundness.
One thing to factor in tho is the effect of turbulence which of course will tend to affect the ball because of a reduced momentum.
Basically, because the ball is lighter, it takes less of a force to move it during its trajectory.
On the other hand, to offset this, you also have to factor in the reduced surface area, the force (for the same wind effect) will be less than .68 because of the reduced surface area; from rough calcs, it's about a 50% reduction in surface area.
Richmond has done an awful lot of testing on this product and it has been done under rigorous conditions but I suppose the acid test in anything new like this is when you try it ... you can have stats coming out yer ass but picking the marker up and firing the damn thing beats all them stats.
I spent about half hour on the phone with Chris Lasoya a month or so back, he has been involved in the testing and development and he told me he would use it in a heartbeat when playing ... 'bout says it all for me really.
