Rear bag filller

[Wiseman7187]

Hi everyone
Hope your all well.
I have a question hopefully I don't spend too stupid for asking.
I have recently brought a seb rear bag for my rifle but am not
sure what filler to put in it.
I was going to use sand but then read something about blasting
Grit being used and thought I'd ask everyone.

What filler are you using in your rear bag and why?

Cheers everyone.

Grab yourself a 25kg sack of Garnet from your local automotive paint or engineering supplies. It should only cost a $1.20 or so per kg by the bag. Works well and extremely heavy! (One of the cheaper aspects of this sport!)
