How to test the accuracy of my gun?

[tokyo2020]

I do not have a gunsmith vice.So how can I measure the size of grouping my precihole NX 100 scorpius makes?
Suggestions please.

learn "artillery hold"
or use sand bag

shoot few shots at diff. distances on a target

measure group size

voila you have tested your gun

Step 1:

Jugaad #1: You can get a gun bag stitched from old denim pants and fill them with rice/sand etc - makes it nearly as good as any vice.

Jugaad #2: Take a few really soft pillows, make a pile and prop the rifle at the balance point. Take an old sock - fill it with cotton etc or any small pillow and prop the butt.

Step 2:
Cock & Load the rifle.
Rest the balance point and butt so that rifle stands on its own and points NATURALLY at the target without you holding it.
Shake it a bit to see if its stable. If not adjust the rests/rifle until you find that sweet spot of perfect balance and alignment.
Get behind your beauty without disturbing her aim, and press her back into you gently (iff you know what I mean).
Gently lay your hands on her stock and your finger on the trigger, keeping her point of aim steady.
Squeeze, not pull, the trigger - backwards into yourself.
Keep the sights on on target until you hear the bang..
Repeat few more times.
Do the math..

Dear Tokyo,
If you are a new shooter , it is not easy for you to determine the perfection of your AR till you get used to with it.
You may get worked up unnessesarily , blaming entire thing on gun.
If you have any old shooter near by , just call him and he will do the job for you.
If you can maintain 2" grouping at 20 mtrs at this stage , it is good.
