in the factory rifles,savage makes a 110fp in 300wsm,and i'm not sure about 300wm anymore.remington makes the sendero,and i'm sure others make rifles capable of 1000 yard hunting at prices that wont break the bank.in my opinion the 7mm rem mag is the lightest i would go to shoot that far.and heavy per caliber match boattail bullets like sierra matchking,berger,hornady amax ,nosler accubond.there are custom bullets avalible too,just search this site.heavy high bc bullets will retain energy levels to those distances.it only gets better the bigger the caliber you go.the 300wm with 200-210 grain match bullets work well for me(208 amax in savage 110fp)then there is the 7wsm,7stw,7rum,300 weatherby,300rum and the 338rum,340weatherby.these too can be had in factory rifles,but maybe without a heavy contour barrell that i would be looking for.if money is no object, a custom built rig is the way to go.the sky is the limit,lots of 338 wildcats that shoot the 300 gr smk at tremendous speeds/energy.my.my.02 cents,jason
