alrighty, the deal is i sighted my rifle in back in june when i got my bushnell elite 3200 10x40 MD and all was well. i sighted in with a load of sierra 100gr sbt's and then when i changed to 105 a-max i used the same powder charge and they shot about identical. SO, later on i lessened the powder charge to get more brass life but didnt check my 100 yard zero. and i went and shot at 100 yesterday and today and it was an inch and a quarter low at 100. could this b from the 1.6 grains less imr 4350? i had the drops figured out and shot the load at 860 yards saturday, so now that i had to bring it up 1.25 moa at 100 will all my drops b that much less??? or is it not that simple? thanks for any help!
