I'm trying the OCW test for the first time. I'm looking for a load for my factory Winchester 70 Super Grade in 30'06. I'm shooting 180 Sierra Game Kings with H4350.
I started with 56.0gr and moved up to a max of 59.1gr. Shot 2 foulers that were damn good at the center of the target, wish I remembered what they were. Then shot the following;
4 @ 56.0gr ~ 2726 fps >
4 @ 56.3gr ~ 2737 fps >
4 @ 56.7gr ~ 2762 fps >
5 @ 57.1gr ~ 2773 fps
5 @ 57.5gr ~ 2805 fps
5 @ 57.9gr ~ 2819 fps
5 @ 58.3gr ~ 2839 fps
4 @ 58.7gr ~ 2860 fps >
4 @ 59.1gr ~ 2880 fps
Wind was from R to L from 1-4mph with gusts up to 7-10mph. Not an ideal day for testing.
It looks like a good node from 56.0 to 56.7, and also 58.7 looks good. I'll load up 56.4 and 58.7 to try again.
Does that look about right? Am I doing it right?
