I am thinking about buying a savage model 110 in 300 rum. I was thinking of rebarreling to a 338 rum or 338 edge since it is a 300 rum already. I dont have the rifle yet but i would like to know what the max mag length is? is there any modifications you can do to make it longer like a wyatts box for a remington? what is the best way to go about doing this? i saw a post on another forum where a guy said he modifyed it to get ~3.9" in the box. is this with the blind mag or a hinged floor plate? also the rifle right now is a blind mag box, how hard is it to turn it into a hinged floor plate? i dont really care for the detachable magazine unless i can get it to feed good and get me a longer COAL. anybody have any info for me thanks
