What kind of sabot did you use to be able to load that .458" bullet?
It is an MMP HPH-.457/.458-50 cal Orange sabot. I use that same sabot in all of my inlines and the GM LRH barrels.
Right now I am getting excellent accuracy with the 300 gr shock wave EZ Glide sabot and the 300 gr XTP (.429") and crush rib sabot out of my GM barrel.
I am a little surprised that you need to use an EZ Glide or a Crush Rib in a GM barrel. All of my GM barrels shoot the HPH-24 or either of the Harvester regualr black sabots. Wait I take that back - a regular Green 44 cal might be tough to get down - I do not use them.
I an a lifelong Nosler user so it is what I use in my ML's for hunting also - but they are getting so darn expensive I may have to change.
I really can to say anything bad about either of the two bullets of your choice - there has been a lot of animals harvested with them. I am old and have not bought into the pointy bullet theory - especially at ML speeds + I have had XTP's separate lead from copper, so I stay with the Noslers.
What the picture does not show is the internal damage the hydrostatic shock of the Nosler did to the animal. Both lungs were jello as was the bottom part of the heart was gone.
