    Illegals overrun Springfield Ohio

    Yes, if you defend yourself and harm a Haitian dem voter, the FBI will be knocking at your door.

    Illegals overrun Springfield Ohio

    They told us of the “fundamental transformation of America” but the sheep didn’t listen. Springfield is just an example of hundreds of cities in this country, especially in states like Ohio, Pennsylvania, Wisconsin, Michigan, where millions of illegals have been dumped by the dems to...

    Arbor Press Vs Single Stage...need your vote :)

    A little background would help. Are you new to reloading ? What level of precision is needed for your shooting? ie, are you just hunting or banging steel, or PRS comps, or are you looking down the Benchrest or F-Class rabbit hole?

    Shots Fired At President Trump's Butler PA Rally!

    Brings to mind the Godfather scene when Sollozzo finds out his attempt to kill Don Corleone has failed. “He's still alive. They hit him with five shots and he's still alive. Well that's bad luck for me…” Must be what the entire dem leadership is thinking.

    Question on Redding competition shell holders

    Sorry my explanation was not very good. I have a Manson 308 go-gauge that is 1.630” base-to-shoulder datum. It chambers in one of my FTR rifles with easy bolt closure. I stick a piece of normal aluminum foil (measured at 0.00045”) on the base end of the gauge and it is difficult to close bolt...

    Question on Redding competition shell holders

    I believe the method you describe is what many reloaders do. There’s nothing wrong with that method. However, as @Ckleeves said, if your fired brass is not fully fire-formed to the same length as your rifle headspace then you may be excessively bumping the brass and you may not get a...

    Does any ballistic app or software have a graph that shows the LOS in relation to the bullet trajectory?

    AJ occurs in the first several yards of bullet travel and diminishes as the bullet precession cycle ends. But the angular correction maintains for the entire flight of the bullet. Whether or not it’s enough to provide enough vertical jump to answer your question is a tough one. Bryan Litz...

    Does any ballistic app or software have a graph that shows the LOS in relation to the bullet trajectory?

    You’re missing the point. In all my posts, I have never indicated the bullet travels above this line of departure. This is because it’s an insignificant point and not relevant to the bullet’s trajectory. Go back and read my posts.

    Does any ballistic app or software have a graph that shows the LOS in relation to the bullet trajectory?

    An object, be it a bullet, ball, or person, cannot fall from a height if that object is never at that height. The bullet is never at the height of the line of departure except for the brief moment at the tip of the barrel. After that, it starts its journey on its parabolic trajectory.

    No use responding to the low-IQ flying monkey. Not worth your time or attention. Best to just hit the ignore button.

    Does any ballistic app or software have a graph that shows the LOS in relation to the bullet trajectory?

    I’m not trying to be argumentative or mean spirited in this exchange. Sorry if it seems that way. I enjoy a healthy exchange of ideas. Thats how we learn. I expect you and @Steel+Killer have a good grounding in exterior ballistics. Sometimes semantics get in the way of learning. The...

    Does any ballistic app or software have a graph that shows the LOS in relation to the bullet trajectory?

    You are of course correct. They rise because the launch angle is positive. Muzzle velocity is a “vector” (which has a direction as well as a strength) that can be split into its horizontal and vertical components. If something is moving at a positive angle to the horizontal, think of it as...

    Does any ballistic app or software have a graph that shows the LOS in relation to the bullet trajectory?

    Yes bullets do rise, unless you are referring to the trivial classroom exercise of a launch angle equal to zero. They rise relative to the point of departure and the earth’s surface. Learn basic ballistics before you start to insult others.

    Does any ballistic app or software have a graph that shows the LOS in relation to the bullet trajectory?

    That angle on page 42 is the launch angle and McCoy sometimes refers to it as the “ gun elevation angle.” The launch angle is a key parameter in the kinematic equations. The line extending from that angle is never used.

    Does any ballistic app or software have a graph that shows the LOS in relation to the bullet trajectory?

    The earth’s surface is the standard reference point with regard to external ballistics and not an imaginary line in the sky. Robert McCoy’s book, “Modern Exterior Ballistics: The Launch and Flight Dynamics of Symmetric Projectiles,” is considered my many professional ballisticians as the...

    Maggie’s I hope Hunter is aquitted

    He’s the son of a POS dem being tried in an overwhelmingly dem state. acquittal or hung jury. This is like trying to jail Joe Stalin‘s son in 1943 Russia. End of story

    Does any ballistic app or software have a graph that shows the LOS in relation to the bullet trajectory?

    “…the drop related to bore axis being the least important, with bore axis labeled as 'Laser Beam' in Windrider's picture. It is not a drop that is useful for anything out in the world…” Precisely put! This phrase from @Tanstaafl needs to be memorized by shooters seeking a firm understanding of...

    Does any ballistic app or software have a graph that shows the LOS in relation to the bullet trajectory?

    In all fairness to @Steel+Killer, he DID NOT say the bullet rises relative to the boreline. He said it rises relative to the bore. That’s the physical and real part of the rifle not the imaginary boreline.

    Does any ballistic app or software have a graph that shows the LOS in relation to the bullet trajectory?

    ^^^correct. The bullet rises relative to its launch point until it reaches the max ord. He’s referring to the imaginary line associated with the bore axis (line of departure, Boreline, etc). The “drop” associated with this line has been the source of much confusion with new shooters trying...
