[QUOTE="Stammster, post: 2088009, member: 114381"] I started a thread on this topic a few months back. [URL unfurl="true"]https://www.longrangehunting.com/threads/obt-method-barrel-length-vs-velocity.250415/[/URL] My conclusion is OBT is like a stopped clock. It’s right twice a day. None of my best shooting nodes correspond to the calculated ideal OBT times. Not even within 20%. This is across multiple guns, calibers, powders, bullets, etc. I have better luck shooting 0.3-0.5 gr increments and finding the accuracy nodes that way. Then refine with 0.2 gr and refine and determine repeatability. [/QUOTE]
