I have searched and found nothing on the impact on water with bullets like this, so I dont know how many people happen to randomly fire shots at water, but the particle effect no longers looks like it use to compared to what i rememmber when I first got the alpha, i wouldnt say it's an improvement.

basically the particle effect remains a constant size, no metter the range.

see the screenshots, i shot at the water at different ranges, and you can see, even from a primary weapon, the water looks like it explodes at a distance. this can be replicated with any non explosive weapon so far. I really dont remember it looking this way before.

the second pic is a much clearer example, through the scope is at a distance of just 3km, look at that impact from a single bullet! {F18645} {F18646}
