I found the published BC for Shock Waves somewhere when I wqas looking for it to see what the 50/40 200gr SW would do. It is one of the BC that I believe it does shoot flat. The Sectional density is a bit higher than most 300gr bullets to. I chorny the 110 gr load I like in the Triumph at 2200+ and the 150gr load the Omega likes is over 2300 along with the high SD that makes it the best 200yd load in my guns even though the longest shot I have made with a MZ was 180 and I did that with a PRB out of my Hawken which is a copy I made of the one in a ST Louis musiem.
