Re: Terminal velocity 308 win Question

Here is amax data

MV = 2800 Bc = 0.475

500 yds = 1933 fps

600 yds = 1785 fps

700 yds = 1648 fps

800 = 1521 fps

Hope this helps

St.

Thanx Kiwi,the BC of the TSX should be about identical,it holds TV better than I thought it would at that range,should be adaquate for thin skinned lopes.
