25 yard versus 50 foot POI adjustment,

Post by zanemoseley on 2/17/2018, 12:36 pm

I'm thinking of shooting a 50 foot indoor match tomorrow but my pistols are zeroed at 25 yards. I don't feel like going to the range today to experiment so I was hoping you guys would let me know what your adjustment is from 25 yards to 50 feet. I'm shooting 22 and 45.

No change for me using red dots. I don't think there would be any change with irons either.

yeah what Len said I'm not seeing any change. I used my ball gun last month at a indoor match and didn't see any change with it also.

50' and 25 yards are the same for me with the dot; with irons it varied by venue so I had to keep notes.

Start with your 25 yard setting, be diligent in calling your first shot accurately, and move your sights boldly.

You know, just like you would under any other circumstances.

If you use a dot sight and aim at the center of the target, then no adjustment is needed.  However, if you use iron sights and/or aim at the 6 o'clock area of the bullseye, then the point of impact must be raised when going from 50 ft to 25 yards.  This is because the size of the bullseye increases from ~ 3.07" (NRA B-3 50 ft target) to 5.5" (NRA B-8 25 yd target) in diameter with the center raised ~1.25"on the 25 yard target. 

For my RO, that's 10 clicks of the rear sight (1/8" per click at 25 yards) for a six o'clock hold.  Other guns vary by the amount of elevation per click.

My RO is one click up from 50 ft to 25 yards shooting irons. Dot stays the same.

While I'm not inclined to change my post on this topic (just yet), I must admit that my .22 with iron sights did not appear to need any change in elevation when going from a 50 ft target to a 25 yard target.  The target size math seems OK, but I think something else is occurring so the zero is effectively the same for a 25 yd 6 o'clock hold on a B-8 NRA target as shooting a B-3 NRA target at 50 ft.  I found this through trial-and-error (i.e shooting a 25 yard match with a pistol zeroed in for 50 ft).  Maybe it's just me.

All true but being weak in math I installed the Aristocrat Tri-Set Adjustable rear sight. Now I just click and relax.

Iron sights- When zero is at 50 yards, my 50 foot group point of impact with be low using a 6 oclock hold.
  Not enough to make a sight adjustment. Just try to hold tighter. Less clearance between the front sight and the bottom of the black bullseye. 



I make my final sight adjustment on the results from timed and rapid fire targets. I tend to hold more day light between the  bull and front sight. 
 When going back to slow fire, hold a hair highter or lower as needed.

No more that 4 clicks different, at the most.
