The rest and base bag arrive last night and I am wondering if there is a special type of sand I should use to fill them with.. (I will be shooting .308 cal iber if that makes a difference)
Thank you.

Joe,
Typically front and rear sand bag rest are filled with a heavy founder sand.
This is a very fine, heavy material.
As it is not always readily available, good clean playground sand can be made to work.
Bags will not be as heavy, which will make them easier to move during ones shooting.
The positive is that it will make them a whole lot lighter to move around and transport.

Without presuming to know would be best for your needs, I have found that the finer sand used for sandblasting will usually make the bag heavier than when filled with 'playground' sand. Sand sold for sandblasting is readily available in different grain sizes and is very affordable. Auto supply stores often have some or can tell you where to get some.

Along intuitive lines, I would avoid crushed glass used for sandblasting because of its sharp edges. What would be the problem with rounded grains either from used mineral blasting grit or as from the beach as long as it is clean?

Thank you; I think a trip to the auto supply store for new sandblasting sand is on my weekend agenda.
