Sigh in Procedure with hunting rifles
1. For most rifles in 30/06 and with the standard do it all 165 gr bullet,
Zero in for 200 yds.
2. Take your time, bring more than what you think you need for ammo
(all the same brand) do it right, let your barrel cool off a bit between
shots, Use a semi soft rest under the forearm not the barrel, shoot prone
Try to pick a day with little or no wind.
3. Set target at 200yds. Start with 3 shot groups for rough zeroing and
finish with 5 shot groups for fine zero. Shoot carefully, no hurry here
4. Keep your last target and mark the range, date, shooting position, ammo
type and weather conditions. This is your 200 yd zero target.
The cross hairs and group center should be exactly the same.
5. Go to 100 yds set new target and fire 3 shots exactly at the bullseye.
6. Confirm where the group is (Should be a little smaller group and 2 to 2 1/2
inches higher.
7. Keep target, mark same data as you did with 200 yd zero and go to 300
yds and set new target
8. Carefully shoot 3 shots at the bullseye and note where the group is
centered. It should be a little bigger group and about 8 inches to 10
inches lower.
9. Keep target and mark data as before.
10. Your rifle is now zeroed in for 200yd and you've got a good idea as to its
trajectory at other distances
In this case you'll be
(a) Approx 2 in high at 100 yd
(b) Dead on the money at 200 yd
(c) Approx 8 in low at 300 yd
11 Extrapolate any distances in between eg approximately 1 inch high at 150
yds and approximately 4 inches low at 250 yd. Using this method you'll
very close to shooting dead center all the time with a little forgiveness
thrown in for shooter error
