Witch one of thees bullets is the toughest/has hightest weight retention - Hornady InterBond, SST, Nosler AccuBond, Swift Scirocco II? MV should be around 3,100-3,200fps.
Interbond. I have had great accuracy success with the 6.5 129 Interbond in my .264WM at just over a chrono'd 3,100+ fps (the exact figure escapes me). It however is too tough for me as I like my projectiles to expand/explode and remain inside.
A few BS/estimated velocitys posted earlier.
