Compared to the 25, does the 30 have significantly more drop say at 75 yards , with 900fps ? And what are any pros/cons if favor of the 30 over 25?

Consider making your own determination.  JBM Ballistics is available on-line.  Just input basic information such as B/C, MV, elevation above MSL, ambient temp, optic height above bore, various zero distances, lateral wind speed, etc. and revelations will occur....

If I remember correctly from middle school  gravity is gravity. Same speed same distance,  each should drop the same amount. The BC will make a difference but unless one is a brick and the other is a boattail it shouldn't be that bad.

I think I’ll stick with .25 . I already have one but it’s an older Chinese qb that I had resized . Shoots great just in the 500fps range . Also already have a 22 so was considering adding a 30 to collection. Anyway this will be my first Repeater so still something new. My Hammerli Pneuma 22 has been doing dang good for 5 years in .22 at 700fps. Cost 250$ 5yrs ago. Still excited about newer higher end shopping . Also while it’s hard to get within 50yRds of a PD , it’s fairly easy to get within 75-100yds here in Amarillo ! Thanks everyone
