RE: Ballistics for the 30-30
hope this helps. with 100 yd. zero with 150 grains bullet
1/2 low @ 25yds.
dead on @40 yds. this is your first zero
1/4 high @50 yds.
about a 1/2 high @75 yds.
dead on @100yds. this is your second zero
3/4 low @125yds.
2- 1/4 low @ 150yds.
you could pretty much aim dead on out to 130 or 140 yds.
