I love the ETip, or at least the .277 130 as it’s the only one I have experience with but it has been stellar out of the 270Wby. This one hit a bull quartered away at about 150 yards second rib from the back and came to rest under the hide after going through the opposite shoulder.
And like Tinman and others have said if given the choice I usually stay higher through the scapula and off the big joint. But sometimes I don’t make the perfect shot. Had I known exactly where the first one landed I might not have sent the follow up, but I probably would have anyway it just happened to land a little lower than I’d planned.
