thanks 4 your 'help' nigel, but i had got that far on my own , do i measure from the outside of the holes or the middle?

[charly hunter]

from the out side and then deduct the bullet size which will give you the exact center to center.

Hi Blackjack,

 

Give this ON TARGET PRECISION CALCULATOR a go, not used it myself yet but its free to download.

Had a go with the ON TARGET PRECISION CALCULATOR myself last week. Simple to use from a digital photo but apparently easier if you scan the target as the software is able to determine the actual size without having to be told how big the target is. Not particularly good groups compared to that expected of a bolt gun but they were fired through my service issue L85A2 at 100m and are well within the required specification for service issue ammunition.

How does the programme cope with one hole groups?

JUst downloaded and used this software. Cracking stuff..

Ronin. The target i used had 10 holes all within a .488" group. I could only tell the software where 6 of them were. All it needs to know is where the outer holes are to calculate the group size.

 

Or was that a joke?..

No it was a serious question, cheers!
