Hi guys, I just wondered if there is any link between RPM threshold and BHN?
Does using a harder cast bullet allow you to push the RPM threshold higher for a given twist?
The main reason I ask is because I hit a brick wall at around 1600fps with the Swedish Mauser and I would like to push it faster whilst maintaining accuracy!
I was using a Hardball alloy of 2/6/92, could I achieve much more with Linotype or is that wishful thinking?
