On what pillow should my bullpup rest for maximum precision? Sand Bag? Bipod?

I like something that will settle and stay like sand for instance. A pillow May tend to bounce around more.

One day it hit me that other than buy a sandbag, or have sand grains leak out of the bag and scratch the Finish, which did happen to me one time, I could buy a ready to go 2 lb bag of rice at the grocery store for less than $2. I've been using small rice bags ever since. They work too.

If I may add something that I found useful regarding technique, take a cue from golfers in the sand trap. Before they take their shot, they give a little wiggle to their body so their feet kind of dig into the sand and thus the sand doesn't tend to move when they make the actual shot. So I like to get my hand that's going to be resting on the rice bag since that's how I do it, and kind of Wiggle the hand down into the bag of rice before I actually take my shot. It seems to provide a more stable shooting platform. There's my two cents.

Here is some advice after learning the hard way.  Don't use sand.  After a while mine turned as hard as a rock.  You need hard (your gun) to soft (rest).  An old friend of mine suggest poly pellets:

Don't fill it to capacity - maybe 90% or so.  You won't be disappointed.  I think a pillow would be too soft. 

Maximum precision...something like this.

I’ve used grain for filler (using retired pant’s legs), but if ur storing them outdoors (I use an old mailbox)... Weevils, tiny beetles, will gnaw small holes in the cloth and make a mess inside.

Ur trying to shoot, and bugs come crawling out onto ur arms and such.

I used kitty litter for mine and it has been good for several years but it is heavy. I think the poly beads would work great but haven't tried it yet.

Pretty much a 'bag guy'...there are a whole bunch of them filled with various things.  Sand,crushed packing peanuts, rice,...big ones and little ones.  Pretty much a mix and match kind of thing, eventally it gets well supported and pointed the right direction down range.

However, the one bullpup at hand does seem to like a bipod. Most bullpups are going to need a high rest... they're already kind of top heavy and unstable...the bipod seems to work at least as well as bags and greatly reduces the tip-over factor.

If you like bags try one of these sets. Sand Sock the three weigh the same as one small Caldwell bag. If you hurry you can still save a penny. ?

They all have an elastic band if you want to have it on the gun. You don't notice any weight.

I've found these mini tripods to be VERY stable. They go from legs flat out to standing.

I did modify mine to accept a quick release top for under $10.

Stable enough to balance a gun. I will use a small bag on the rear sometimes. (Ignore the scope location. I'm using this gun next weekend in a 25 meter competition and liked not having to move way up on the bench to see out of it.)

If all else fails even the diminutive Mutant Shorty will work on a Caldwell Stinger full rest.

It may also be helpful to use a smaller bag of rice or sand under the bottom edge of the stock.  I watch alot of videos of competitive shooters.  Its interesting to note that many of them use their off hand to cup the rear of the guns stock and pull it tight into their body

Nice options, thanks! ? 

The rear bag — that is something I yet have to try, as up until now I only shot springers — with a front bag for supporting my off hand....

I can see how that will give a lot more stability.

About putting the gun onto a ball joint tripod with a picatinny quick release: While shooting do you keep the ball joint loose, or do you tighten it so it does not move?

I use it with it tightened once I have it pointed where I want.
