Adjusting sights from 25 to 50 yards. OR adjust hold?

How many clicks up would I normally have to go from 25 to 50 yards? For example , I have a Les Baer PII 45 acp.  Its set up for six o'clock hold for 25 yards ( to shoot about 2.75 inches high at 25 yards) with Federal Gold Medal 185swc.

When I move to 50 yards AND will still want six o'clock hold ( 4 inches high on 50 yards target ) how many clicks up I would normally have to go ?

OR is it better to just use center hold at 50 yards? 

Any help is appreciated.

I still use 6 o’clock hold. I come up 4 clicks

Try 6 clicks

Try zero clicks first. 3" high from point of aim at 25 is 6" at 50. Bullet might drop back in X. All depends on load.

You have a good answer above:  4-6 clicks.  I use 5.

Back to my zero answer. I was just playing with my ballistic calculator. a 185 gr SWC with a bc of .114 and a muzzle velocity of 850 fps has some interesting numbers. Iron sights about 1/2" above the bore and sighted in at 75 yds. To match observed performance. Would print about 2.9" high at 25 yds and 3.2" at 50. Those numbers change a bunch as velocity goes up or down. I used to shoot hardball center hold and never changed my sights between 25 and 50. I didn't have this handy calculator back then but looking at it now I see those hardball rounds would have been about 1" high at 25. If you never change them you don't have to worry about where you left them.
