RE: reloading a 300 Ultra-Mag
Well, at least you didn't take to the extreames I did, and have a 500 dollar rebarrel job. It worked wonders.
Like I tell everyone, this is a finicky cartridge. Don't expect it to be like a 308Win with 15fps velocity spreads. Get used to to those 70fps spreads. But when you find your combo, it can be very satisfying.
