[QUOTE="RockyMtnMT, post: 1186724, member: 7999"] I ran calcs and a 10" twist with the 103's at sea level would have an sg of 1.23. Just stable enough to fly accurately. At sea level I don't think it would be enough to hunt with and not have that bullet tumble in impact. Also you would be sacrificing 8% of the bc. I ran those numbers at 3700fps. I am not familiar with the Roy but thinking this would be a top end velocity. What is your altitude? Steve [/QUOTE]
