I shot 1000yds in Maine using a 8.5-25X50 Leupold and a 20MOA base on top of a .30-378Wby Mag. It would launch a 220SMK at >3200fps.
1760 is another story alltogether. Has it been done ?? YES. Can you do it with a 300 with a 10 twist ?? YES
But just guessing . . . your gonna want more gun and/or a faster twist bbl.
A 40X scope would be great also. --- SAWMAN
