Re: 30 cal. 180 scirroccos BC?
I have a .300 Jarrett, similar to the .300 RUM. I have used both the 200 gr. smk and the sgk. On those closer shots , out to 200 yds, these bullets have always blown apart in the animal without exiting. You might want to take a look at the Nosler Accubond 200 gr. as well as the Swift. Though I have not yet used either of these bullets, I have a box of Accubonds sitting on my bench as my rifle prefers 200 gr bullets. I did try the Nosler Partition, but accuracy was lousy in my rifle.
