That’s an interesting level, Steve. I haven’t ever heard an individual mention that in advance of. I don’t assert to generally be an authority in metallurgy, so that would surely be the case. And that i commonly acknowledge that Like several exam, this wasn’t perfect. I heard a data analyst say 1 time “
The velocity wasn't what I am in search of at this point. I am aiming to be inside the 2900fps realm but right now With all the 60gr load I am sitting at 2843fps average. Not sure .8 of a grain will get me considerably more velocity.
