The goal of this post is to index useful resources for the 300 Whisper on the web. If you know of a good reference I am missing, please post below and I will update this first post.
hello!
Does someones knows where i can find some balistic data for the 300whisper in 220 gr or if not for other bullets?
More precisely i m looking for the height loss at 50 , 75 ,100, 150 yards...
sorry for my "frenchy" english
Sounds like you you need a ballistic program and a cronograph. I'd recommend the Ohler cronograph and here is a web site that will help you with some online ballistics, http://www.eskimo.com/~jbm/ballistics/traj/traj.html
I have no experiance with 220 grainers as I prefer the 240 grain Sierra HPBT. For every day shooting and hunting I set my zero at 82 yards, which makes me 2" high at 50 yards and 2" low at 100 yards. I use 9.2 grains of H110 with a CCI SR primer.
I have also been working on a 125 grain load, 2400FPS velocities are easly achievable but I haven't found a consistant load yet.
