OCD’ing Yourself Into a Corner

Just a couple of photographs I took recently. I ran into a shooter who was, as I recall, buying Sierra Match bullets and then making them, “more match” by grinding off the OTM (Open Tip Match). I believe his term was, “squaring them up”.

Frankly…I had never heard of such a thing. Thought it was kind of weird and took some photos for posterity. No…that’s not truthful. I thought is was goofy as hell! A little google searching shows that he didn’t pull this idea out of his own butt. Instead it seems there is a OCD support group website that is fronting as a rifle forum.

I can tell you right now, if you ever see a video of me trying to out engineer Sierra by modifying their work, call the cops or the psych ward. Because something ain’t right and I need a welfare check.

    It would be interesting to see groups shot with both modified and unmodified bullets. If there’s a whole group of people doing this you’d think at least someone tested the theory…

    • Everyone believes there is gold down at the bottom of the rabbit hole.

      Maybe it makes a difference? Maybe it’s measurable at 100 yards? I doubt it. Maybe it’s measurable at 1000 yards? But I doubt even world class shooters could pull it off.

      So…1000 yard shot? World class shooter? And can design bullets better than Sierra? And engineer a modification better than factory? While walking on water?

      I didn’t know Jesus was in the ELR game?

        I’m definitely skeptical on the benefits, i just think it would be interesting to test. I guess if they makes them happy more power to them. All about shooting and having a good time or something right?

        • Right. I just bet he’s never tested it. It’s become something akin to a superstition.

    If it makes him more confident, fine, maybe he’ll shoot better because of that. But if he thinks it makes a difference, no. Too close to the axial center of rotation. Real world example: tape a few quarters to the end of one ceiling fan blade and turn it on. Now tape the same stack of quarters to the same blade back by the motor and turn it on.

    • Hey…I have no issues with the lucky rabbit’s foot!

    My understanding of the OTM is that the small open tip actually causes a negative air pocket, in essence a tiny air bubble, in front of the bullet during its flight, increasing it’s aerodinamic efficiency, allowing for pinpoint accuracy. Why anyone would modify the design without any ability to do any testing much less go against a manufacturers design is just moronic. If you’re getting sub MOA groups from the get go, why bother anyway. If it ain’t broke, don’t fix it.

    • That was always my understanding. Or at least something close to that. But I am no Boo-let Doctor. I suspect they are getting this idea from somewhere legit, but perhaps they have dropped the math justifying it?

        Anythings possible, Marky. I guess it’s just the idea of grinding the tips off of an expensive box of match ammo has more of a cringe factor than I can tolerate.

        • I’m right there with you. I had to resist the urge to vomit out my visceral reaction when first presented with this theory. But in fairness, if people just did what the experts told them to do, progress would grind to an almost standstill.

    Bullet pointing. Nothing new here. I don’t do it myself but I know these folks aren’t taking perfect hollow points and making them more perfect… Theyre taking damage from a bulk package of 500 bullets and simply straightening the tip out to create a more uniform tip. Look at the tips of your huge box of loose HPBTs next time. If a variable (albeit very small) can be removed… well damnit some people will take the time to do it lol. Not this guy but variables exist in this game and the less… the better right?

      Will it make a difference at 100yds? Hell no. Will it make a difference at 1000yds? No that’s your shitty shooting technique… Or is it?

      • His thinking, as he relayed it to me was, HP makes more drag. So he grinds them off.

          Hahaha okay yeah that’s just plain dumb… might help with expansion on targets though right? lol.
