Bartlein ocw results

[Markg90]

I’m kind of stumped at ocw results. Shot the first time at 100 yards then did a seat depth test then tried to fine tune the ocw at 200 yards. I find ocw is GREAT on smaller profiled barrels on hunting rifles but seems like I always have trouble reading the results when I try it on a heavier barreled rifle.

If you're seeking education, understanding, and knowledge of combustion and propulsion, then the only OCW that matters can be found here: https://ocw.mit.edu

It's a fool's errand. A Rorschach test.

Pick a speed.

...though, there's always the chance that maybe you didn't break-in your barrel correctly, or that your bullets are going to sleep..?

I would say 41.8 is your charge weight and 2.128 bto your seating depth. I would move that combo to long range testing and see how it tracks to begin building a ballistic profile. Overall it looks quite forgiving and shoots most combinations really well for a precision field rifle.

Put the Chronograph away! Outside of a rough estimate of velocity the ES data is worthless.
