find a savage axis on sale , work over the trigger , install a boyds stock and then splurge on a really nice prefit barrel and have lots of money let for a even nicer scope .
add about 600.00 and do the same with a rem700
unless you have reamers already , myself , I would push the shoulder as far forward as possible and give it a 40 degree shoulder . a case capacity of around 80 grains of water should be possible , 338 win mag is around 86 grains of water .
