I have learned to take any 25 yd paper sight and move it to 50 then 100. I don't trust a 25 yd sight by itself for any caliber. Seems whenever I try to adjust a 25 yd sight to equal a 100 yd zero it never works out and I still have to adjust at 100. Probably something I am overthinking or something. I always go 25 to get close, make big adjustments at 50, then fine tune at 100.
