In my opinion, there is no need for any bigbore that pushes a bullet of 300 grs, up, soft, or solid, faster than 2500 fps! Tests have been done that show there is a detramental effect on bullet performance when pushed at higher velocities, there is a window between 1900 fps, and 2550 fps where bullets work best on large animals! This fact is the reason the most successful cartridges since the 1890s till today, opperate within this window! You can't argue with success!
