That 286 TSX is WAAAY too long in my view for anything less than a true magnum cartridge. At 1.5" it eats far too much powder room. Even the 250 TSX is about 1.375", which exceeds the length of the 286 Nosler Partition. I will never use them for that reason alone. Then, they are not necessary and over priced, again in my view. The 286 Nosler Partition will do anything they will do and leaves ample room for expected powder charges.
I don't know what pressure Barnes used in their testing, but from a 26" tube they record less than 2300 fps, which will limit the useful range to about 200 - 250 yds if any expansion is wanted.
The 286 Nos. Part. from my rifle is useful to 500 yards on larger game like eland or moose where velocity is still over 1800 fps.
