RE: BM3 +Shockwave 300s from an Omega
The 200 gr Shockwave works well on deer also. As you reduce from 300 -250 - 200, you will likely need to reduce your powder charge for best accuracy. Try around 95-100 grains BM3 or 777 using a 200 gr Shockwave out to 200 yards. That light grain bullet still maintains it's high profile length like Precision QT & DC poly-tips -- all three designed for good co-efficiency.
