Clark,
Your shots are under a 100 yards and you're even commenting about adjustments?
?
I am at the South end of Mercer Island using the Issaquah range for 11 months a year.
One month a year I stay in Eastern montana for deer, antelope, and elk.
Sometimes two months a year when I go in the spring for prairie dogs.
I sighted the 6.5-06 Dumoulin I built this year to 100y and worked up loads at Issaquah. Then in MT I made marks on the turret to 600 yards before hunting started. I then shot a doe at 629 and 250 yards with that rifle. The 300WM Mosin I built was sighted in to 500 yards in MT and shot a buck at 250 yards. The 6mmRem I built never got past Issaquah.
I typically build 3 rifles a year, but I buy a lot more scopes than that.
