Sand for rear bags

[HeatherW762]

Scuse my ignorance but why Chromite sand compared to - say - plain old builders sand? Don't they both just fill and weight down the bag? :? :?

Smaller grains, heavier.

Used for castings.

For a full and nerdy description this

Heather,
For F/TR, where you shuffle and squeeze the bag for every shot, heavy sand doesn't matter - I often use a 'bean-bag' - a nylon bag filled with small plastic pellets. This makes aiming much quicker. It's also easier to lug about! World Champion Russell Simmonds uses one.

for Open F Class, the shooter is attempting to emulate a proper benchrest set up. The back-bag stays put - solid as a rock - all adjustment is made on the front rest. This is where you will benefit from the heavy sand.

Cheers

sign92 for the enlightenment guys. So, in fact, to get the best of both worlds you need a heavy material at the bottom of the bag for rigidity and something more squishy at the top/in the ears to allow better/quicker aiming. Hmmmmm...... :-P :-P

You need to be careful here:

F2.18. The contents of front and rear bags will be a dry, finely (< 5 mm) divided substance such as, but not limited to sand, gravel, or grain, packed loosely enough so that the bag will be visibly deformable by pressure of the range officer’s fingers.

Well, not really - if you are a bag-squeezer, you don't need a heavy bag - your hand is providing the 'solidity' in the rear support.

The heavy sand comes in when you don't 'manipulate' the bag back - it simply provides a rock-solid support for the butt.
