How do I get ultralight fill into a shooting bag with a small flap?

[Mojave]

I have an Armageddon Bench Rest bag and I filled it full of heavy sand and it was 80 pounds. So that doesn't help me much.

I dumped out $40 worth of playground sand and ordered $80 worth of ultra flight fill.

How do I get it in this thing?

Very carefully.

Some sort of automotive funnel or a reloading funnel worked for me. Or chop a water bottle in half.

Long ago I took a piece of 308 brass and cut the base off of it. I stuffed the biggest funnel that would fit into the case and taped it with electrical tape to the case. You could do something similar with a piece of copper or brass tubing. I'm sure I did what I did because the piece of brass was handy at the moment.

Static Guard and a funnel and it goes in easy.
