hi everyone im new to this whole gun thing and im having alot of fun. i have already bought a fair amount of guns and i am trying to set one up for deer hunting and plinking out to 800 yards. i was told by a friend to buy a gun that uses a 6.5*55 sweedish so i bought a tikka t3 varmint in stainless.another friend sold me his never mounted nightforce 3.5-15*56 varmint scope to put on it.the scope has a clearer view than any of my others but i dont understand how i am suppsed to accuratly see what im aiming at way out there. also i was told to try different loads to see what my gun likes. how does this work.i am useing berger vld bullets 140gr with imr 4064 powder. thank you for reading my long winded post.
