I was at the range for a few hours today trying to find out what shoots better out of my rifle. I'm shooting a Win model 70 300wsm with a McMillian edge stock topped with a Swaro Z5 3.5-18x44. I started out at 100yds and was nuts on. I shot the best groups I've ever shot. Not quite all 3 touching but damn damn close. This was with all factory ammo - Fed premium trophy copper 180gr shot best at 100yds. Nosler Accubond 180 shot ok but not quite as good. Now let's bump it out to 200yds. I'm all over the place! Same rest same scope setting. Everything identical. I'll get 1 4"low and 2" left then 3"low and 3" right then 4" high and 2" right. This went on for quite some time with both brands of ammo. I eventually got frustrated and called it a day. I know this isn't exactly long range but previously I had always sighted in at 2" high at 100 and called it good. Today I wanted to actually try to zero at 200 but didn't have much luck. Any thoughts, comment or suggestions on what may be wrong or what I might be doing wrong?
