Thank you for the replies I forgot to add, he that which promotes growth and vigour some 5 shot groups that were exactly the same. 

Fast strings group to a 3/4" 5 shot group, slow shots produce a horizontal string . 

Hello all 

I've reloaded some 143gr Eld-x for a friend of mine and his new rifle . 

During development he's been getting horizontal strings . 

All ammo is cleaned once fired brass all trimmed and COAL is 2.810" 

Rifle is shot off prone with bipod and rear bag 100 m from target 

Below are to diffrent groups of exactly the same powder weight bullet etc .

The difference is the one group is 1.5" below the other 

The horizontal string is shot with 2 minutes between shots,  the standard 3/4" group was shot one after another 

Below is a picture of horizontal string the other group picture hopefully attached below 

Every thing on rifle is tight and has been checked . I'm not shooting the rifle my mate is I always thought horizontal strings were driver error or something loose . 

Can anybody shed any light .
