Zeroing scopes

[DTom75]

Okay, I need a little help here. I would like suggestions at what yardage I should zero my scopes on for different calibers.

Bolt Action .17 HMR: 100, 150, 200 yds?
Tactical Semi-Auto .22LR: 50, 75, 100 yds?
Bolt Action .270 WIN: 100, 200, 300, 400 yds?

Any help would be deeply appreciated!

Thanks!

I zero 22s at 50yds and my hunting rifles at 100 but it depends on what you consider your range limit for hunting. There are any number of ballistics calculators on the internet that can help you figure bullet drop at various ranges with various zeros.

17hmr - 100
22lr - 50
270 - 200

I like a 300 yard point blank zero for .270 for hunting use (130gr bullet path is no more than 3" low or high across that distance) and 200 yards for target/LD competition use. A 135-150gr bullet in .270 has a very flat trajectory so why not make use of it.

I would think 150-160 yards may be also good for the .17 especially for varminting as it has a very flat trajectory till it takes the elevator to the basement from drag.

I agree with 50 yards for .22 rimfire.
