    Hyper Stabilized Bullets - Jim Boatright

    So let's look at a 750 gr. A-max @2800 fps from the barrel at sea level. It hits the sonic barrier at 2050 yards. At that range you need 79.35 MOA with a 100 yard zero. With a 500 yard zero you need 71 MOA. Just little bit over 8 MOA more... WOW!!...I think I can handle that ...

    Thanks Jim, that makes total sense..especially considering super-sonic flight dynamics. But what about subsonic? I do realize the point of your design is to extend the range and accuracy by keeping the bullet above Mach well past two miles for ELR. Most competitors in the KO2M are shooting...

    Jim, Does the radiused rifle grove also decrease some of aerodynamic drag imparted by conventional rifling to the laminar air flow as the bullet spins thru the air? If so, wouldn't a swedged hammer forged design rifling similar to what H & K uses be best? I guess one could take it one step...

    I would think that the design of the the muzzle brake gas pathway would have a larger impact on the initial accuracy. But, I've heard that all boattail bullets have some wobble as they leave the barrel and then will stabilize within the first couple hundred yards. Some 50 BMG bench rest shooters...

    THEIS, I see that you are running a Schneider barrel. What is the length will you be using? Would you happen to know the max length they can machine? Thanks

    Hyper Stabilized Bullets - Jim Boatright

    I am ordering up a 28" 7 twist barrel this week for a 6.5 saum. The 346-gr Mk II ELR sounds really interesting, especially if it is shot from a 416 Barrett case! Only problem I see might be finding a slow powder for such a large overbore...

    Jim, Any updates on testing info of the larger ELR bullets?
