Is anyone mixing lead pellets and sand to fill their rear bag? What ratios of sand and lead work? I assume the ears are exclusively sand? Are there any hard sections between the bag's ears? Alan you may have some experience here?

Dave,

Yes I am toying with a lead mix. I'm using winchester 7.5 shot, which was the smallest they had in the shop, and mixing it 1 to 1 by volume with my normal zircon sand. It seems to mix well - thought the lead might go to the bottom, which would have been okay, but as far as I can tell, it remains homogenised. Do you know what the main problem is? Its too damned heavy for my back . The Protector DR bag is about like a car battery to lug around (13.5Kg), and I'm seriously considering reducing the lead ratio.

Dave can you PM me with your e-mail address please. I've been trying unsuccessfully with your old one.

Message sent Alan. If your back is going, then FTR offers less clutter to clean up after shooting so you can get back and score on time. . Would be interested to hear from others what rear bags they use and how they pack them. Anyone use talcum powder? Yes, it helps funnel the sand in. David.

Protektor DR rear bag. Fill the base section with sandblasting garnet, install the bag in a strategic location in the back of the ute and drive around for a few weeks on the typical country roads here. Its settled and packed in well, got a top up now ready for use. I have regular playground sand (from eldest childs sandpit) in the ears. Just need a rifle to use with it.

I put lead shot in the bottom of my Seb bigfoot. Topped up with garnet. Garnet only in the ears. It comes in at a heafty 12kg and is nice and stable. I found i don't need a rear plate any more, which is good since ftr lost their spikes.

Will the lead shot fall under the "not limited to..."?

F2.8. The contents of the front and rear bags will be a dry, finely (<5mm) 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.

Won't a heavier base work better?

indeed not limited = unlimited if you can lug it around

I just bought a 25kg bag of garnet sand to try in some rests, but why not load the thing chocker with bird shot ? I think its overkill but may be worth a try ....

For F-Open at least, if you're allowed spikes in the base, then the amount of friction between bag and base determines how much the bag jumps sideways under recoil. Friction will be directly proportional to the weight of the bag, so double the bag weight and it'll require double the force to move it sideways.
