So for the last year or so we've had HSM loading the 350gr Swift A-Frame in our 457mag ammo. The bullets are outstanding, accuracy reports indicate they shoot better than the Kodiaks we used to load for alot of guys, and terminal performance has been superb. Jim has one shot through a Muskox and one shot into a bison that he recovered both weighing around 345-349gr and opened to about .85. Another shot through a grizzly and came through in exellent shape although it lost a little weigh smashing through a bunch of vertebra.
What I'm proposing is to buy some and load them up to 2500fps in my 458. I figure that even if the front half comes apart I'll still have basically a Nosler Partition. I really like 350gr bullets in the big fella, flattens trajectory somewhat and lessens recoil as well. My problem is that aside from the TSX there is no premium 350gr bullets redily available, I guess the Swift is about the same cost as the Barnes offering but it'll be a good excuse to reload and shoot more.
Anyway, thoughts and ideas appreciated.
