This video from Boondock Ballistician delves into the science behind Open Tip Match (OTM) ammunition, explaining its manufacturing process and impact on accuracy. The instructor highlights how bottom-up manufacturing provides better control over bullet base geometry, crucial for minimizing projectile instability upon exiting the barrel. While OTM rounds are designed for precision, the video also discusses their limitations, such as lower ballistic coefficients and unpredictable drag at transsonic speeds, and emphasizes that for most shooters, the performance difference compared to standard FMJ rounds is negligible.
