Re: Need help on a un filled bag
Since I'm usually schlepping my rear bags around in the field, I stay away from the sand, heavy sand, bbs, shot solutions. For a weight/stability compromise, the poly pellets work for me (hobby store variety that are slightly smaller than bb diameter).
I didn't think to try the airsoft pellets though (good idea).
I've also found that the fill material diameter and the % of volume you are actually filling make a difference. For me, I like slightly smaller than bb diameter with the volume fairly "full". This seems to keep the bag formed to the contour of my stock/accupod across mutliple shots. Of course, sand would be better but I'm not willing to carry the weight.
I recently had a bag that uses very small diameter poly pellets with low volume of bag actually filled. It's too "springy" for my tastes, i.e., it doesn't hold it's shape at all. Topping it off with larger poly pellets seems to have done the trip (with minimal weight added).
