Can anyone tell me at what range the velocity is down to 2000 fps ??
B.C. is .359

I'm away on an off grid job and don't have access to my books and tables

I emailed Woodleigh's about the terminal velocity on the 303 215 and he said it has a thinner jacket for better expansion at 303 velcities.
He didn't give a lower impact velocity but he did mention it was thinner than the 308 180 grainers jackets

He also mentioned knowing several 303 double rifle owners in Australia who used the 303 215s with great success
