SC ELK
At this point were I to shoot a conical @ an Elk it would be the 460 Bull Shop or No Excuse... I prefer the Bull Shop as Dan will size it to fit your bore and then it becomes a 'slip fit' - load it just like a sabot - no short starter needed.
It is a very accurate bullet and even has a pretty decent BC for such a big slug.
I shoot it with 90 grains of T7 @ 1500+ fps.
