Caldwell TackDriver Bag with Durable, One Piece Construction and Non-Marring Surface for Outdoor, Range, Shooting and Hunting

Filled with polybeads which worked very well, but very heavy to carry although very stable. Compromised with polystyrene balls which were much lighter but not as stable. As it's for an air rifle, it's not really a problem. Excellent grip on the fore end of the rifle with both methods.

After read about what to fill the tack driver with I bought a 10L, 6Kg bag of Amazon's corn cat litter it filled the tack driver with a little squiggy room, using the whole bag of cat litter. Bargain compared with buying the filled tach driver. Don't get it wet!

Rellene de arena de silicio tal y como recomienda el fabricante y está perdiendo. Quiero recalcar que nunca llegue a usarlo solo lo rellene y mientras lo rellenaba me di cuenta que perdía. Personalmente me esperaba más por el precio ya que tengo sacos de arena tipo kettlebell más barato y que he usado durante 3 años, sin perdida.

Great shooting rest, read the information though you will need to buy your own media to fill this. Not a hard process at all. Great bang for your buck and the reinforced rubber handle makes moving this around on the range a breeze. Your zero process will become seamless if you have good fundamentals and use this. You will see no sway in barrel if used correctly. Fully stuffed its approximately 10lbs maybe just feels real awkward when carrying but other than that, you can literally bring this anywhere you want

USE PLASTIC PELLETS/BBs FOR FILLER This is the best rest you could get. It supports and cradles your rifle, and in most cases, you dont need a rear rest. It is top quality. You will be best served buying the unfilled bag, and using plastic pellets (similar to the kind used for weighted blankets). I ended up needing about 12 lbs worth to fill the bag, but it flows, and sits nicely, and you never have to worry about moisture.

I had one of these years ago and gave it away. Wish I had of kept it so I bought another one. Works very well at a good price.

Got this yesterday and filled it, but haven't taken it to the range yet. I haven't seen any of the quality issues others have reported. I like the size and weight. Filling took about an hour and I used a ten quart bag of Zilla synthetic desert bedding and a long transmission funnel. Yes, there's only one fill port, but it connects to each of the four bag chambers, so just add to each one in turn, no big deal. The ten quart bag of Zilla was enough with some left over.
