Sorry for the confusion.
I'm shooting at a range that only has a 25m range. I will be attending a course and the recommendation is to have my weapon zeroed for a 50m range. Is there a way I can do this on the 25m range?
Typically having your sights adjusted to impact 1" low at 25m will have you bang on at 50m. This will give you the 50/200m zero.
Use a ballistic calculator. https://www.federalpremium.com/ballistics_calculator/
If you are zeroed at 25m enter that as zero range. Use 25m interval, and the program will show you the hold over/under at 50m.
No you don’t need one, the OP asked what the difference in POI would be and it is an easy way to calculate it without shooting. Also FWIW 2 clicks on a T1 at 50m is about 0.25”you need a ballistic calculator to go from 25M to 50M???? 2 clicks down outa do it
