Re: Velocity-Looking for Insight
Are you sure 3200fps is possible with a 210gr bullet from a RUM, without running dangerously excess pressures?
I don't have one, but reviewing your cartridge in QuickLoad, and running what-ifs, I have to conclude that you'll never get there.
QuickLoad shows me that 90gr Retumbo & your bullet equates to SAAMI Max. It's gets ugly from there.
Maybe I'm missing something though...
