Thanks for the feed back.
I currently using a two point sling with shoulder pad. I sling it cross my chest and usually have the strap tight so it doesn't wobble. The problem with that is the barrel stands almost a foot above my head and pushing between tree branch and bushes, the barrel kept getting caught! I really hate putting stress on the barrel because of the thin material used.
I'll look into a VSR. I wonder if there is a bullpup bolt action sniper out there.
