Searching the intertubes, it appears that the 25m zero is a popular one for 9mm carbines.  What zero do you prefer?  Does anyone have any trajectory charts?  I'm specifically interested in 115gr FMJ performance out of a 16" barrel.

50 yards

Why?  What differences in POI have you noticed at distances other than 50 yards?

I also prefer 50 yards for my Mp5K-PDW clone. Shooting 115 9mm I am about three inches low at 25 yards. I have never tried shooting it farther than 50 yards.

25yards....and here is why....  (when you click on the link....wait......the chart will come up in a couple of seconds )

Why use a 25 yard zero for a 9mm carbine?

I have always zero'd PCCs (most of which wear RDS, FWIW) at 50 yards and continue to do so.



The article forever4 posted above (I've seen it a few times, here and elsewhere) makes a very strong argument for 25yd zero IMHO and, honestly, if I were starting over again today from scratch, I'd go with that.  As it is, I've been using 50yds for a very long time and am quite used to it and, beeing a stubborn old dog, I am averse to new tricks.

If you are dialed in to a certain range, no reason to change. Starting from scratch, give it some thought.

Thanks, all.  I'll go with the 25 yard.
