Range Time and Assumptions…

Well, it was back to the range again today to try one more time to help my friend and his dad zero the AR with the EOTech on it. 

This time the batteries were new, and they ‘said’ they had bore sighted it…

So… Just in case I put a target out at 50 yards, hoping ‘not’ to need it…

First three rounds at 100 yards, nothing… again…

Moved to the 50 yard, and it looked like they were shooting high, as I could see dirt fly ‘above’ the target.  Told him to aim for the bottom of the target backer, and low and behold, three rounds about 3 inches from the top of the target!!! 🙂

So, about 32 clicks down…

And three hits at least around the bull…  WTF???

No grouping at all???

Rechecked tightness on everything, try that again, still no grouping…

Lemme try that thing!  Three round group one inch low, one inch right.  Okay, two and two clicks, and try it again, and all three are in the red center…

I hand the rifle back, and no grouping again!  Now I ‘know’ the rifle is on, so whatinhellisgoingon???

Ask the son to shoot it, and his group is about 4 inches wide and high right by 4 inches… Huh???

Put his dad back on the gun, and still no group!  Lemme try that again; and they all group in the center!

Now I’m totally confused…

So we talk through sight alignment, and how to use red dots… Low and behold,  his dad had misread the manual, and they were trying to put the red dot on top of the front post! 

Told them just use the red dot, and IGNORE the front post completely, and all of a sudden the groups were in the center and 2-3 inches…

Assumptions WILL screw up your whole day… Sigh…

At least his dad is now happy…

Went over to the trap range to get my normal humiliation, and miracle of miracles, I went 20/25 and 21/25!  I was accused of practicing, but I literally have NO idea why I’m suddenly so much better, as I haven’t shot a shotgun since the last time I got humiliated…

I’m just gonna chalk this one up to experience, and call it a day…

Range Time and Assumptions… — 12 Comments

  1. Remarkable, the little things that can change everything at the range. Things like…. pointing the rifle at the target.

    Assumptions indeed.

  2. Some days are just better.

    Years ago, I was asked to shoot skeet with a boss on his family’s personal range. I’d never shot skeet before, was using a borrowed shotgun and couldn’t miss if I wanted.

    Damned if I know how that happened. Some days are just better.

  3. Carteach- SO true… sigh…

    Jess- Yep, blind hog day! LOL

    WSF- You just might be right… I didn’t think about that! Problem is can I ever do it again???

  4. Wow – never would have thought about putting the red dot on the front post . . . .

    Congrats on the trap score – not to shabby at all!!

    We had a free steel shoot at our chapter house to introduce folks to the sport – really nice turnout. “Sadly” – “the boy” shot a 3.53 . . . . going to hear about that one for awhile . . . 🙂

  5. I co witness my iron sights with my red dot. That’s a fairly common practice. Dad just forgot you need to get the red dot sighted first, then get the irons adjusted.

    Well done all in all.

  6. eia- Neither did I… sigh…

    Gerry- He was using the red dot AND the front sight… Not co-witnessed…

  7. Can you bore sight an at like a bolt gun, by sandbagging the gun, pulling the bolt and using the eyeballs and patience? Always seemed to be better than a laser bore sight back when I was shooting a 7 mag.

  8. Robert, you can, BUT every time you adjust on the EoTech, just like adjusting on a scope, you basically have to redo the boresight (and try to get it exactly the same)… NOT easy in my experience!

  9. It has taken me the better part of two summers to get comfortable with a scope, after 50 years with open sights. Fortunately, my scoped rifle doesn’t have iron sights, or I might have been tempted to use them.
