I took my first trip to the range yesterday. I have never owned a rifle with a scope before, and was a little unsure what to do, but the rangemaster (John) at the range (Elm Fork in Dallas) was very helpful. I bought a Savage 110 in .30-06 with a Simmons 3-9x50 scope a few days ago. I was shooting Federal Premium Vital-Shok, 150 grain nosler ballistic tips through it. Here are the results. I was going for 2"high at 100yds. Puts it roughly 0-1"low at 200yds, which is about as far as I plan on shooting. 1st shot: 1.25"left and 2.75"high adjust scope 2nd shot: .75"left and .75"high adjust scope 3rd shot: centerline and .75"high 4th shot: .25"right and .75"high (3rd and 4th holes touching) adjust scope 5th shot: centerline and 3.5"high 6th shot: centerline and 3.5"high (5th and 6th holes touching) adjust scope 7th shot: .25"left and 2"high 8th shot: .25left and 2"high (7th and 8th holes touching) pack up and go home. I figure I am close enough. Is this accurate enough at 100yds, or should I be looking to do better? Any advice would be appreciated. Also, how much variation can I expect when switching to different ammo (Winchester Supreme 180grain, Power PointPlus)? Does this require recentering the rifle? Should I be keeping notes, as far as what ammo shoots where at what scope settings? Thanks for your help!
