I have settled on my long range load for my 300 Win Mag. I will be using the 220 SMK. Velocity is right at 2800 fps using H1000. I shot that load yesterday prone and sitting with my bipod. I shot two groups of 3 shots each at 500 yards. First group was prone and measured 4.2". Second group was sitting and measured 6.9". All 6 were in 7". I do not hunt from a bench. The rifle weighs 9# and has a 3-9 Swarovski. So I cannot imagine taking a shot at beyond 500 yards. It is also shooting the 200 Nosler Partition well enough out to 300 yards and point of impact of the two loads are similar enough that the same scope setting will work out to about 400 yards. Rufous.
