RE: its time for a new one
8mm, 338, 358 and up for bore size. The 338 federal, 338-06, 358 Win, 35 Whelen all good to 300 yds and the big bullets get the job done to. And then there are the magnums, 325 Win SM, 8mm Rem Mag, 338 Win Mag, 340 Weatherby, 350 Rem Mag, 358 Norma Mag. Lots of choices, do you want sometning common or not so common? The 9.3 mm comes in a couple versions, 9.3x57, 9.3x64. Short action or long? Lots of choices.
I've shot some deer with a 338 win mag and it works great, actually I think it give less meat destruction than a 270 win and you can shoot from one end of a deer to the other without fail.
