I used the Barnes max load of H4350 with 130 XLC in the 26" barrel of a M70 300 Win Mag for just under 3700 fps. The furthest I shot it was 500 yards but of course it was very flat shooting.

Never got to use it on anything but I bet it works well. smile




The 280 Remington is overbore.

The 7 Rem Mag is over bore.
