Thread: Why plateaus in velocity graph

I have tried it. After shooting the first string I shot a second, the plateau from the first string wasnt there in the second. I could have shot the second string first, or third. It did give me an idea of where max might be but that's about all. I posted similar results here https://www.nzhuntingandshooting.co....38/index2.html
Iv Had a good look at barrel timing and that comes with its own set of issues. I ran some of my best loads through the theory and got noting but random results. Trying to use QL to determine the exit time is hopeless, its just computer modeling and there are to many variables to expect any consistent level of accuracy from it. That shows in the random outputs compared to real worl results as well eg fro my 243ai its right on the money but the 280ai its not within 150fps with any of the loads I tried.
The OCW I think works ok but its not far off a what Id call a stanard work up.
My opinion fwiw is these techniques are mostly smoke and mirrors that become accepted through a combination of confirmation bias and to small test samples.
But its little more than an opinion so ..
