On the bullet jump thing, I just tested 45 Colts in a new to me Browning 1885 Single shot rifle in 454 Casull. I found, like I always do, is that Hornady XTP's will do a single ragged hole. I was only testing at 25 yards as it was just mainly a chrony/load session. but the XTP's were stunningly accurate making the jump, and they were the most accurate load tested in my 7.5" Colt New Frontier in 45 Colt with .457-.458 throats.

I tend to shoot mostly lead bullets in most of my guns, but when I want to see how some particular combination of gun/loads/parameters will work for accuracy, it has usually been XTP's that will tell me.
