PCC Zero Distance

Scott Hearn · Feb 3, 2017

Where do you set your zero? Running 147s, I set mine dead on at 15 and it definitely shoots "uphill". At 25 with a center hold on the upper A-B zone it will go completely over the target. Wasn't really expecting that much difference. Probably ought readjust out to 25.

I zero at 20yrds & don't hold over or under for anything

I set mine mine with a 25yrd zero but haven't had it in a match setting yet.

I went to re-confirm my zero today after swapping out my diode to a larger MOA. My zero is a little off, I'd have adjusted it but I forgot my screw driver. Anyway, this was 50rnds at 20yrds unsupported.

IIRC mine is set at 25 yards.

What switch did you make, Wall? From what to what and why?

No ****??? That sounds impossible. I zero at 15 for USPSA. I can't imagine ever seeing a head shot only at 25 in a match. So I guess I've never tried it. I'll give it a whirl tomorrow.

I was running a 2moa diode & swapped it to a 4. The 4 is brighter & faster to pick up on the buzzer. At uspsa distances there's really no need for a dot that small.

Damn, I was hoping you had an extra 4 laying around

Good to know. Thanks!

Your talking about 4"+ difference from 15 to 25yrds.
That sounds odd. What sight & mount?
What is the height over bore, is it stupid tall or something?

That's what I was going to ask. Must have a super tall mount?

Actually it's only 2.95" from my hold and one round did barely clip the perf, but I mean just friggin barely.

The sight height is part of it, it's a Burris XTS-135 sitting in a Burris tall ring. Similar setup to a Aimpoint PRO, Comp M4, etc., 5mil dot. Evidently these 147s shoot like mortars if zeroed short.

Please post up what you get and your setup. I probably ought to just grab a C-More for it, but this has a 5mil dot and it's not doing anything else so I thought I'd throw it on this gun.

Just zeroed my MPX at 15 yards with a holosun 510c (eotech knock offf) and moved back to 25. Sure as ****! I was just catching thevtop of the head box. So I dialed the zero in at 18 yards to bring the 25 yard hits down a little. Here are the results. I'm starting to think a 25 yard zero maybe where it's at.

mikey80 · Feb 5, 2017

I zero at 18 yds.

My only hold over is on targets less than 5 yds.

105 gr bullets make the Scorpion shoot like a ****ing laser gun.

slemmo · Feb 6, 2017

I would zero a PCC at about 35, same as my open pistol so you dont have to work out both hold over and hold under. You're catching the bullet before it has peaked, just like a 50/200 rifle zero. And that's too complicated for my brain under stress :girlwacko:

I was thinking some super light super fast hand loads would be tits.

Well I zeroed mine at 25yrds and thought I could fake it and make it thru a USPSA match this weekend. Looks like I better get back out and check some 5,10,15,20 yards holds.
