.223 ballistic mystery...

[C Ward]

What kind of mount is it , couldn't tell from picture ? 35 in lbs on the cross bolts seems kinda low . Also the PEPR mounts the cross bolts aren't seated all the way at the factory and have to go trough 3 or 4 torque cycles before they have pulled up tighe against the shoulder .

Not sure if it is online or not but there is a video from the Magpul movies , not the Hodnett stuff but the extra footage with Cayden Wojick about che king scope setup and checking NPA with closing your eyes .

It is a Warne, came with a scope I bought used a while ago.
I believe it is this model:

Looks like you are correct, it calls for up to 65 pounds.
And up to 25 pounds on the caps, although Vortex calls for 15-18, so 18 pounds it is.

When you set parallax do you just dial to the number on the knob or actually check that the scope is parallax free at that range?

[DireWolf]

The scope has parallax adjustment and I do adjust it for range.

^exactly what I was thinking when I read that...

Move my head slightly and make sure the reticle doesn't move in relation to the target

Parallax isn't going to cause inches at 100 yards errors . This seems more of a mechanical/ tolerance stacking error . First thing is better ammo and determine if the barrel is acceptably accurate and confirm the scope is tracking.

I would exclude the scope:
I started by zeroing at 50.
Then, without any adjustment, I shot my 100yds target: consistent hit 2.5" high.
Proceeded to adjust for it (2 .5 MOA down, 10 clicks with a 1/4" value) and got a group, huge as it was, on the crosshairs.
I will shoot the box next time I go out, hopefully with the Sierra bullets.
The issue here is not accuracy: I know that this barrel sucks, and I know that because I am a much better shooter than that (the picture below is my personal best with my 308, 3 rounds group at 100yds without adjusting for wind).
The second picture is 2 consecutive shots at 550 yds (I would have shot a third but Those were my last two rounds).
I may not be competition material but I practice consistently.
The issue is why my my group printed 2.5" high rather than 1.5" as it should have.
If my shots were between 0.5" and 2.5", making a 2" group, yes, I would know it's the barrell, or the load, or me for that matter, but they printed quite consistently at 2.5" high.

This community is awesome. There are tons of great shooters on here with probably hundreds of thousands of rounds sent down range.


Watching from afar on my COVID covered couch my thoughts are Minute of bad guy doesn’t care about that extra inch of zero

[C Ward]

I personally would start by zeroing at 200 yds with decent ammo .

Cross over zeros work fine for green e types but there is enough slop that when shooting reasonably sized targets it can cause misses .

My ballistics program shows cross over for 200 yds with 223 / 556 at 46 yards .

Also the problem with shooting close is moa / mrad are an angular measurement so a relatively small error up close is multiplied as the distance increases . I always zero at the distance I want the zero at .
