Ifn it were me i would probably use my tried and tested 'elk' bullet. The Nosler .458/300 Partition PP. This is a rifle bullet and it is an excellent performer for me on elk. I shoot it with 110 grains of T7-2f in an MMP HPH-.457/.458 - 50 cal Orange sabot.
This is a pic of the recovered .458
I would also like to tell you that there is a new bullet on the market that might also be of some interest to you. Depending on my personal hunting experiance with a smaller bullet on whitetail early in this upcoming hunting season I may make the move to one of these new bullets to hunt elk with this fall also. These bullets work on a different theory of operation than the normal bullet so the concept is a bit difficult for 'old foggies' like me to grasp - but I am investigating...
The bullet that I might try is a Lehigh .458/300 grain - again a rifle bullet and currently being used by 45-70 shooters. The reports that have grabbed my interest have been some very good reports of performance of the bullet on Buffalo hunts. Here is a picture of the bullet ont he right standing next to Barnes bullet.
Another bullet that is being offered is the new .458/275 grain Lehigh. Depending on some velocity tests that I will run hopefully this upcoming week - this just might be what I use this fall on elk.
It probabably is not a good idea to recommend a projectile a bullet that I have never tested but from everything that I found while shooting this bullets in a testing situation and the observations i have made from other in hunting situations... they may have a great future.
I will tell you if today right now... if I had to make the immediate decision without my own testing - i would go with the Nosler... I know that I am going to get accuracy and terrific hydrostatic damage to the internals.
