I will be putting a 1.5 to 4.5 weaver scope on it, (detachable of course), so a cartridge that shoots farther does have more appeal. Also, I know John Taylor did not speak highly of the 405. But that was on African game. It just seems to me that Teddy Roosevelt is the only selling point to the 405!! Nobody else talks about it beyond that. I also wonder about getting brass a few years down the road? The 9.3 seems to be more consistantly available.
