Hey guys, i picked up a winchester model 70 in 270 wsm and tried it out. I got .323" groups at 100 yards. With a pos scope that I just trew on there, the original stock, and off of a bipod with factory ammo. I thought i just got lucky so i shot again. It did about the same thing. Let my buddy shoot it, he got a .375" group. Think I should build it or leave it alone?
