More data on the micro poly rear bags.
Just a thought though, there is much personal preference w/regards to rear bags. Everyone seems to have their own idea. The optimum situation is to be able to design your own or have them made to your specs. I'm getting pretty much tired of adapting "me" to some other person's idea. This is especially true as the requirements become more stringent as in real, true, long range hunting.
I made the camo rear bags in the below pic. The leather rabbit ear bag, was purchased in 1966 and filled with 'special' sand and rice until just the other day. Rice and sand must have been in vogue back then.
Notice the difference in construction (my wife was fairly impressed). The bag on the left is thinner than the center bag. (The lady at the fabric store showed me how to do it;))
With these three bags most of the various shooting angle conditions in combination with a decent bipod can be met. The bags can also be used 'on end' to get more versatility.
They are very light.
The left most bag weighs 490gr, the center bag 700gr and the rabbit ear bag ~1400gr. Most of the weight of the leather bag is the leather. Thus a total of about 2590 grains or ~0.4 pounds. Compared to a Leica 1200 LRF Scan weighing in @ around 1 pound.
As for attaching to the rifle. They may be attached to anything desired (one of those personal preference things).
A couple of targets shot using these bags are in the foreground.
As far as rating them, they can be made to achive the 'natural rest' quickly, are solid in position like a rock and they do not diminish the APS rifle's capability's in the slightest.
BTW HP: The stuff goes in the 'post' Monday......
