Brad: Back in the bad old days I used to load 150 Partitions(screw machine) with the "old" O'Connor load of 58.5 H4831.Velocity was 2925-2950 or thereabouts.From one Goens custom with 22" Douglas barrel, it just broke 3000 fps.

I mighta been leaning on things just a hair with that one grin




The 280 Remington is overbore.

The 7 Rem Mag is over bore.
