PVA At distance

Looking at hoying a bag over 120 - 130yds and not sure if my current bag set up would take it.

Boiliein the bottom corner topped up 3/4 with small pellets, 2oz in line on top, tied off with PVA string and then double bagged. To be honest, im not sure if launching any sort of bag that distance would not explode when it hits the water. Have tried putting a few nuggets of foam or a pop up in the bag but at that range its hard to see

Suggestions?

Boat it out?

If it can stand you casting it out , it wont explode when it hits the water, unless you've managed to get it wet while loading the bag, but even then a damp bag will explode when cast. PVA is really quite strong until it gets wet. Just make sure you have pricked your bag to let the air out so it sinks faster and melts on the bottom and not on the way down.
