Welcome to GBO

It depends on the bullet used; where to set zero to and where you feel comfortable at. I like to to set hold over for long distance shooting. It feels more natural to me to hold over for longer shots. I think it is a hold over from shooting 22 Shorts and 22 Long Rifles for years before getting center fire rifles. With that said there really is not much difference between a 75 yard zero and a 100 yard zero. With a 158 Hornady XTP traveling at 1600 fps a 75 yd zero will be .7" high @ 50 yards and 2" low @ 100. A 100 yd zero will be 1.7" high @ 50 yards. A 180 Hornady XTP traveling at 1400 fps, a 75 yard zero will be 1" high @ 50 yds and 2.5" low @ 100 yds. An 100 yard zero will be 2.2" high at 50 yards. Really for deer it is dead on no matter which one you set zero at. Using a 158 grain bullet for varmints/plinking I would set at 75 yards as zero and hold over just a little for 100 yards shots. But that is me. The data I provided are for Hornady XTP bullets, but are close for any bullet that is the same weight, general shape and velocity. Good Luck and Good Shooting.

What is he going to shoot and at what expected ranges?  Mine is sighted in at 60 yards because I wanted a rifle for 0 to 80 yard work on deer, yotes, fox, woodchucks here in Michigan and deer and hogs in Florida.  I even dust crows, pigeons and starlings with it.  It's my favorite "litlle" rifle and the .45-70 is the favorite big.  Sighted in at 60, I can consistently hit the 300 yard gong holding over.  You could probably stand out there with a baseball bat and drive the bullet back to me, although you can clearly hear it clang when it hits.>   I might mention, it may well be the most accurate close range rifle of the not so few I own.  I shoot mostly 158 gr. .357 JSPs and 158 gr. .38 Spec. LRN.

Oh, I forgot to mention, mine does not like 125 gr. loads.

Best of everything for the Holidays.
