PCC Zero Distance

[mikey80]

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:

my 18 yd zero is spot on at 35 yds

Yep, I've not had any issues with my 20ish yard zero.

Sounds strange, unless you have a very low mount you should be way high on 35 with an 18 zero. Try running it through a ballistic calculator.
With a 35 zero you should be about 1.5 inch low on 10 yards and slightly shy of 1 inch on 20.

I did this last night. I compared a 115 factory load with my 147 gamer load using a 2.375" sight height in 5 yard increments out to 100yds. My target was very similar to Jesse's and it doesn't jive with this.

What height? Did you get an MPX or Scorpion? I forget.

I tried to use ballistic AE app which I use for .223/.308 in 3-gun to see where my bullets where going and it was jacked up. I wouldn't trust anything but actual holes in paper right now.

Okay that setup still has a pretty big distance over the bore. Where you getting these 105gr bullets? May have to buy a pack to play with.

Dang Ol' Bayou Bullets, man...

I was zippin' A's like crazy shootings Merle's Standards. That's 35 yds and an 89% score, too.

This one made by a Norwegian dude several years ago is spot on as long as you feed it correct data. I use it for all my rifle shooting.
