So far this gun has been interesting as it can be converted from bi-pod to BR front rest quickly and from monopod to BR rear bag .
I have discovered that from the BR bench the verticle is better with the bipod than the BR front rest and the horizontal is better in the BR front rest . Which led me to start looking at why . It's been my experience so far with this gun that the bi-pod skates about from side to side more so that it jumps up and down under recoil . Hence good verticle but wider horizontal and it all reverses around when I change to BR front rest .
I'm still in the research and trial and error phase on this problem. Like it's not a big problem as the total groups size is still good but I would like to eliminate more horizontal using the bi-po and get the group more round . Have not been able to do any prone on the ground at targets yet so that may change things also.
Could be me also . Something I am doing that don't suit this rig when using the bi-pod. Every group so far is sub 1.25 MOA and most sub .75 MOA but when you pur 4 in .2 and then one drops out to the left 1 inch perfectly inline with the center of the group it's annoying . Which makes me suspicious it could be me . However I can't loose sight of the fact that the action has limitations and it's not a match barrel and chamber either. However I still think the bi-pod and attachment is partly to blame as there is that difference of grouping when changing rest systems . One of the drawbacks to multiple platforms is it can get confusing as to where the issue is.
