Zeroing 9mm

[eighteenninetytwo]

I posted this on the semi auto rifle board but thought that the latter part of the quetsion might be better and quicker answered here due to more familiarity with 9mm

I have a red dot sight incoming but would like to get to the range with my new Beretta CX-4 storm. The iron sights are pretty high above the line of the bore on it, and I' m not sure if that is common in PCCs but it is what it is.

Question - What distance have people zerod these at previously? and also does anyone have a diagram or information of the ballpark corresponding zero distance further out from bullet drop (ie zero at 20 yards also = zero at 80 yards or something) with 9mm.

Depends on personal preference and usage.

On my Ruger PC Carbine with a simple red dot, I had it zero'ed out to ~75 yards at the range. But then I realize that was impractical as it mostly sits as a home defense/back up weapon, so now it's zero'ed to about ~50 yards. If my target is past ~50 yards, I probably shouldn't be shooting it in an urban setting...

I have a Vortex Spitfire 1X on my CX-4. I zeroed it at 50 yards. Sight correction is not significant at closer ranges until within 7-10 yards where parallax becomes an issue as it would for just about any optic on a Storm. I haven't tested it past 50 yards as it's unlikely that I'd use it at that range.

115g or 124g? I always zero at 25 yds, adjust as needed up to 50 yds max w/ 9mm.

My PCC is zero'd at 25 yds.

If zero'd for 25 yards, where does it impact at 50 or 75 yards?

75 yard zero

I have my PCC zeroed at 75 yards based on Max Leograndis' advice. He says that a 75 yard zero is almost a 25 yard zero, but with benefits. Ironically, I was previously zeroed at 25 yards. But when I went to confirm, my sights were way off. I will try an embed his video and post a 9mm ballistic chart. Max states that this zero works with different bullet weights. I trust his word, he is a PCC National Champion.

25 yards, there is a good reason for it.

Without bullet drop, zero at 25 yard will be "bore height" high at 50 yards, which will be reduced in reality by the bullet drop. Essentially, you'll get a point blank range at all practical distances. All you have to remember is that at very close range you have to aim a tad high, and even that is not necessary unless it's a precise (small) target.

Zero it at "distance you'll shoot," which some people do, and you'll be lobbing it high as soon as you try distant targets. There is never a good justification to zero at close range.

Edit: Just noticed it's CX4 and not PX4. Still, it's a pistol round and not meant for distance. You can zero further out than 25 yards or zero it at the second zero. Make sure you have practically no holdover to at least 50-75 yards.

With PCC you want the maximum point blank range, same as with a pistol.

Zero it at the distance you intend to shoot it the most.

There is never a good justification to zero at close range.

There is a near-zero and a far-zero.
This happens anytime the sights are above the bore centerline.
You should set the far-zero at the range you want to shoot at most commonly and then the bullet is high between the near and far zeros and low past the most common distance that you zeroed it for.
