Good Point Flattop....they(Nosler) go on and on about the neck being so short(300 win mag) and I guess thats why Federal loads them that way. I use standard partitions and have not been affected in any way shape or form. I once in awhile use the CT uncoated partitions. Any bullet that groups well and is heavy for caliber is the best choice...I am not a big fan of ballistic tips but they seem to do real well in 30 cal and larger calibers on big(Elk+) game especially at launch speeds greater than 3100 fps. I saw a moose in Newfoundland dropped like lightning with a 180 BT in a 30-378. There is a lot of BS out there about certain bullets spread by hearsay and our good ole gun writers.
