Not sure this is the right sub forum,.. but it does involve marksmanship and gun handling so,… 🤷 😁
PCC ZERO ISSUE
So I’ve gone and zeroed my PCC Using my carry ammo of Federal HST 147 grain hollow points with my Holosun AEMS red dot at 15 yards.
With my 10” FM9 zero’d @ 15 yards, Im putting bullets thru the same holes. 😎. I’m literally using 1 inch pasters to cover up 3, 4 & 5 bullet holes at a pop!
As I understand the charts,.. I should be shooting low inside of 15 yards. Which appears to be the case. At 10, 7, and 5 yards I’m shooting anywhere from 1” to 2.5”-3” inches low. Accurate, but low. And That’s roughly where the online calculators I used say I should be hitting with the 9 mm, 147 grain HST load.
The issue I’m having is according to the ballistic calculators & charts, (… Which admittedly I am still trying to understand & figure out.) I should be shooting a little high at 25 and 50 yards,… And then it should come back down to zero out again right around 85 yards.
That’s not what’s happening! At 50 yards I’m shooting inches high and POI is moving to the R. At 85 yards. I am shooting even higher and still shifting right. At 100 yards,.. Its still going even Higher & further Right by several more inches. Plus,.. the groups are opening up significantly.
Even if I’ve read the charts wrong,… At 100 yards with a 9 mm load it should be dropping, no? Not continuing to track up.
While I am using a red dot without magnification and with my astigmatism, it blooms badly from time to time. I am wearing my distance rx. And Once I get out past 25 yards I turn the brightness way down to eliminate the worst of any blooming. Even so, shooting at 75, 85, or 100 yards,.. the dot does cover a pretty Significant portion of an 8 inch target. So it’s possible my aim is off. Still,.. I would expect most, if not all of my hits to be dropping not consistently going high & right.
I am at a loss to understand why my hits continue to move up and to the right the further from my zero distance I aim. 🤷*♂️.
Any one have any insights as to what might be causing this?? BTW,.. This issue seems to be present and consistent with my various 124gr. FMJ practice ammo as well.
