I am working on a load for my 7mm right now. I started with 160 grain Sierra Game king, CCI 250 primers, and IMR 7828 powder. I had problems with accuracy, plus seemed to be getting jacket seperation. ( Picking up copper jackets with no sign of lead.)
So I scrapped that and started over. I got some 160 grain Accubonds, and loaded them using Reloader 19. This load shows a lot more promise. At 59 grains of powder, was getting 1 moa with a speed of 2750. I worked up some more loads with 60 and 61 grains, but haven't had weather nice enough to shoot them yet. I should be able to achieve close to 2900 fps. I have high hopes for this load!
