Hi Marakai

I,too, have a fine .280 that I have been intending to shoot. In fact I have acquired both 375 Ruger and 300 Win Mag brass to work with. It seems, from your experience, that the 300 Win option would be easier. The one thing that I wonder about, though, is excessive neck-thickening from the down-sizing. Have you had any issues with the necks?

Thanks
