Sir Bob,
If one can bear to sacrifice a 450-gr TSX it might make a better 400-gr XTSX.
I enjoy chopping the 500-gr TSX only because it might be too long for stability in game,
even though it is superbly accurate on paper from a .458 WM+ at 2250 fps MV (0.19 MOA for 3 shots)
and goes only a little over 1 MOA at 2342 fps MV from a skinny CZ barrel of 1:14" twist.
Loaded to 3.78" COL for those shots, it will not even fit into a SAAMI .458 Lott chamber, as you recall,
and I like to repeat.

Just try to start with a batch of bullets that belong to the same lot of manufacture.

Sir Woods has forwarded this excellent JPEG from his batches of TSX bullets:
