And BTW, apologies to Sir Larry who has been pushing copper WFN solid.
That Lehigh 380-g/.458 copper WFN solid does feed well in all my .458 WM rifles,
when I shortened the COL to 3.200″ instead of +3.300″.
Sometimes just 0.1″ shorter COL makes a world of difference in feeding an FN solid.
It feeds like poop through a goose in my .458 B&M at COL of 2.940″
which makes it a match for the .458 WM with COL of 3.200″.

Bless his heart, Doc M might even be thinking of testing that bullet for penetration too,
and I am sure he could come up with ideas on improving the design.
The best solid performance in MIB media is in the 5 to 6 feet of penetration range.
That translates to about 8 feet or more of buffalo or elephant.
The test media stops soft points much more quickly than FN solids, relatively speaking, just like critters.
Round nose solids veer unpredictably,
hence the joke about the angulation in the bullet trap, midway along, ha ha.
Doc M refuses to test anymore of those!
