Nosler's loads with the 286 Partition and RL15 seem to be the ticket in my CZ550FS. 57.5grs. give about 2300 fps with its 20" barrel with both the partitions and Hornady Interlocks. Accuracy is sub one inch with 3 shot groups, and case life has been exceptional with 14 loads with one batch. Ramshot Big Game shows potential, but I have just started working with it. I hope to take my 9.3 hunting soon, I'm eager to see its effectiveness in the field.
