Mule Deer, John I didn't address your comment on neck thickness in my previous post. I haven't checked that yet, nor have I checked for concentricity on the loaded rounds. It occurred to be that the difference in accuracy between the 110gn ELD X and the 117gn SST may have something to do with the SST being flat base and the ELD X being a boat tail. I like to get within 200yards of my animals so the flat base projectile could offer better accuracy inside that distance. Looks like there's more experimenting coming up.
