Let me/us know how many grains and I'll run it a QL for you.
Thank you!
You are going to show us something new here.
270Roy first
He started(RL25) at 77(3404fps) to 86.5 grains(3797fps).
Standard Weatherby AOL used during these tests but as we know Roys have free-bore galore, which can be very useful!
Once cases become too full(higher loads) they where vibrated down on the side of a tumbler.
Let me know what you come up with.
Cheers
