A large factor in these tests is the .68 paint they are comparing. As we all know the quality of a paintball is mainly down to how well its been looked after.
In the GI milsim tests, the .68 paint was obviously a lot worse than the Evil paint these tests used.
You could see that they were quite happy with how poorly the 50 cal paint performed.
But that wasnt a camera trick. It really did bounce, was less accurate and had poor penetration compared to evil .68 paint.
At least they showed a lot of the setup procedure.
The tests by GI Milsim seemed a lot more 'edited'.
If two tests dont agree with eachother, Id side with the one where they show you more of the procedure.
