I am shooting the 230 grs Hybrid Target in my 300 win mag.

I have a Tikka T3 Super Varmint, with a Lothar Walter barrel. Twist is 1:8 and length is 26".

I use 71 grs of Viht N570 and this gives me 2747 fps. It is not a hot load, but it gives me the best groups at 100 meters.

I have found that the advertised BC is a bit low. I have tested it out 3 times now, in different conditions, and when I put every data into Applied Ballistics on my smart phone, I allways hit high. It can not be my velocity, becuse I need to dial in 3084 fps to get it right, and there is no way I have that speed.

So I have adjusted the BC up from .743 to .770. This brings me dead senter out to 1200 meters.

Is there anyone else who has come up with a different bc, than the advertised one?

Happy new year to all of you
