    4DOF inclined fire error

    Again, this is what I'd expect conceptually. The solver ALWAYS treats wind as horizontal to gravity. It is not parallel to your shot LoS. Your 322 degree wind has a headwind component to it. You are firing at an incline or decline, so that headwind component will have a (relative to your LoS)...

    Which counties outside North America have a strong PRS scene? Rim or centerfire

    From what I gather, many PRS shooters from Western Europe go to Czech or Scandinavian ranges to practice. In Germany, for example, there are no civilian ranges that go beyond 300m and only a couple of military ranges that a person can hope to get access to that will go 800-1000m. The laws in...

    2+2=7, but WHY? Expectations vs reality.

    Take this or leave it. I noticed POI changes from our 100/200yd tunnel to outside in sunlight. I'm not an optical engineer and I don't have the know-how or equipment necessary to properly understand and test this to say anything with authority... I might even be wrong in correlating it to...

    4DOF inclined fire error

    That is from the wind angle. It's pushing into the bullet level with the horizon while the bullet is going up hill, so with wind will hit higher than without wind. In level fire the wind is head-on fighting the bullet so with wind will hit lower, if you were to shoot down hill the head-wind...

    2+2=7, but WHY? Expectations vs reality.

    Yep that's what axial form factor is for. Every barrel (even muzzle devices in some situations) produces a slightly different Cd vs. Mach plot and we publish the average of the barrels we shoot the bullets through, so you may need to bump drag up or down a little with Axial Form Factor. The...

    2+2=7, but WHY? Expectations vs reality.

    Being that far off that close, even with subsonics... to me, screams of something else not being quite right. I'd be looking at your zero. If you tell the calculator you're zeroed at 50 yards, it better be 50.0 yards and it better be spot-on at zero. The closer you do these things, the more...

    What can I do with bullet speed at distance

    Those acoustic targets have limited accuracy, just an FYI. They are in the ballpark, sometimes very close or spot on... but probably not accurate enough to really do much with drag calculations or anything like that. If you could verify one vs. a Garmin or something make sure that in that...

    2+2=7, but WHY? Expectations vs reality.

    If you're using Hornady bullets, and they're in the 4DoF library, it's a no-brainer to use 4DoF. We've shot the bullets on doppler radar to get the exact Cd vs. Mach plot for that specific bullet (No BC involved, no G1/G7 standard conversion. It treats your bullet as its own "standard"). We...

    2+2=7, but WHY? Expectations vs reality.

    If you input what you know to be true MV (Garmin, Labradar, etc.), and you input the correct sight over bore and zero information, then the biggest reason you don't hit where the calculator tells you is because it has error(s) in the drag portion of the solution. BC is an approximation of the...

    4DOF inclined fire error

    Yeah that patch release was a problem... That's about all I'm going to say publicly about that... And again, we're looking into the angle incline thing. 4DoF being different from a BC solver doesn't really alarm me in and of itself. 4DoF departing from reality does. We've tested it before...

    Wisdom teeth removal

    I can feel one on the upper left, under the skin. Kinda been waiting to see what it does, but it's been like 3 years now, about the same. If it pokes through I might have it removed.

    4DOF inclined fire error

    We're still looking into it. We've got reports from several of our sponsored shooters and I've seen these posts pop up from time to time as well. There have been a couple of matches where half of the attendees let us know they were off by a large margin at a specific target. We have gone to...

    Maggie’s What's Your View II

    Lower belt was all chewed up, went to replace it and found out why it was all chewed up... Got on the Ebay but the replacement was for an early model HLV with a 1" motor shaft (mine is 1.125"). Fixed on an HLV-H at work. "Make yourself!"

    Barrel Torque Ludicrocity

    From an accuracy standpoint, I can't remember a situation where higher barrel torque resulted in poor dispersion. I'm sure if you get to the point that you're swelling the receiver ring (several hundred foot pounds+) you can get some problems, but nobody is gonna get anywhere close to that, so...

    Let me talk to Jayden tomorrow. I know he was looking into this earlier this year, but I haven't heard if anything was found.
