    Are you thinking of BC the wrong way?

    Good point on BC's not fitting some bullets; Even G7 isn't always a good enough drag model for some bullets especially at ELR. This is where Custom Drag Models (CDM's) come in. CDM's model the actual drag of a specific bullet, with no regard to a 'standard'. The bullet is it's own standard...

    Hornady 4DOF Ballistic Program

    As previously stated, the issue with the above statement is 'first publicly available...' It is not the first public solver to calculate AJ. If you're clinging to the word 'correctly', that is a marketing twist. A prediction of AJ from a MPM solver is still a prediction. Until it's...

    That's not true. By attaching the acoustic microphone to a hard target, you can detect tof even for subsonic rounds with very high resolution. We did measure MV and all other variables required to calculate the bullet's performance. You can criticize all you want, but with just a couple...

    Hornady 4DOF Ballistic Program

    Radar technology has the potential to be 'all that'. But not all radar's are not created equal. The unit shown in Hornady's videos is a Infinition BR-29015 BR-29015 It states a max range of 800m-1000m for 5.56mm rounds. It is not capable of gathering all the complex data that some more...

    Hornady 4DOF Ballistic Program

    That's a good observation, I'm glad you brought that up because it gives me the opportunity to explain something important. All bullet manufacturers have lot-to-lot variations in bullet dimensions and BC's. Berger is no exception. The big question is: how much lot variation exists...

    Hornady 4DOF Ballistic Program

    This is a reasonable reply, but it's buried in the comments section of a campaign in which so many false statements have been made such as: "... We've raised the bar on calculating trajectories for long range shooters." and "... We're changing everything" and "We're the first...

    Hornady 4DOF Ballistic Program

    Some clarification... There are many types of modified point mass (MPM) solvers which approximate or neglect various terms for different applications; some are optimized for small arms, some for high angle artillery fire, etc. It seems that one such MPM model has been referred to as a 4...

    Scotty, Thanks for your comments. You're correct that I am the Chief Ballistician for Berger Bullets and like you/we said, any critical thinker should consider things like that. Berger has always valued facts and we are all subject to that standard. If anything we put out is found to be...

    Hornady 4DOF Ballistic Program

    Applied Ballistics free online solver uses a library of 500+ measured G1 and G7 BC's and also works with any other BC you input. There are several ways to access AB's 500+ custom drag models but they're all paid, with the easiest path being a $30 mobile app and $1.99 in-app purchases for the...

    Aaron, The first rule of critical thinking is to consider the source. Hornady pays you money to promote their products because you are in the business of promoting things and do a very good job at it. At the end of the day, you're judged (and paid) by how many viewers you have and how much...

    Discussion of new book

    All, The latest book: "Modern Advancements in Long Range Shooting - Volume 2" has shipped and you should all be receiving your pre-orders now. I'm starting this thread to discuss any reactions and questions you have about the material. There are some things in there which may stir up...

    Berger 375 possible?

    Steve, We have shot a small number of these bullets and the results are very promising so far. G1 BC over 1.0, and G7 around .510. I'm getting just shy of 2900 in the CheyTac case, 33" barrel. They appear to be grouping well but IMO it's too early to tell. We've got a lot of shooting...
