Good to see you bought that .458 Ripp. I know you needed another gun.

If you are a handloader, a .458 Winchester or Lott is a doable and fun proposition. A lee factory crimp die makes crimping a snap. Separate seaters for the softs and solids prevents mishaps from seating. If I were going for a mixed bag in Zim tommorow I would pack along a .338 Winchester with good 250's, and a .458 Winchester with 500 grain softs and solids. I would the following week as well.

Any rifle from .300 magnum and up should have proper stock reinforcement(glass bedding and perhaps a crossbolt or two) and relieving of the stock behind the rear tang, and the back of the trigger guard. Good QD mounts to go with good sights on a heavy rifle is cheap insurance.
