I have settled on a bullet made by Hornaday with mag express sabots for my deer rounds. I have not had a chance to try this combo on deer but it should work well in a magnum rifle. I use the 265g interlock flat point made for .44mag carbines and it shoots real well out of my Encore and Scout.

In the encore I load 120g loose 777 with a T/C mag express sabot and these bullets and it is the most accurate 100yd round I have ever shot. It is very close to my .308 in this range so I give that load the thumbs up in my Encore.

If you can use one of the four outboard sighting targets on a standard sight in target you know it is shooting well. Hitting them 1/2 bulls is a rush.
