FAST????
What are you hunting?
Interested in the finished RPM.
Hammers won't have that issue. I shot the frangible 17cal, 18gr Dead Blow Hammer bullet out to 5060 FPS.Word of caution I'm shooting 90gr Bergers out of a 7 twist and the other day they started blowing up, (about 500 rounds on the barrel)
I cleaned the barrel to bare steel. I need to take it out again and see if that cured the problem.

Some light calibers CC bullets publish max FPS.What would/could be the maximum rpm on a cup core bullets then? I guess some might vary between hunting and target bullets?
Good luck keeping a cup and core bullet together at 6.5 twist. They'll be spinning so fast prolly start tornadoes22CM AI 1:6.5TR
