What grain of bullet are you firing in it Kevan?
Looks like the 375 whelen is right in the middle of the range of velocities I was interested in; with 5 rounds in the magazine.
Does anyone know if it's possible to form 375 whelens with a expander/resizing die like a 9.3x57?
In the 375 / 06 I use the 270 Hornady for fire forming and it works well for full power loads too.
I take a 35 Whelen case and expand the neck to hold a 270 gr. Hornady so that the seated bullet is jammed into the rifling when the bolt is closed thus keeping the case straight, let her rip and there you you have a nicely formed 375 / 06 Imp case.
Trim to proper length and reload it..... easy Peary...
