Not sure what you're asking but no my 470 is not a Capstick it is a 470 Nitro Express
And no it's not a super high priced English double either, it's a working mans double from Merkel in Germany.......
The 470 is the standard by which all African cartridges are judged, you do not require anything larger for lifesaving and stopping dangerous game and it is still very easy and comfortable to shoot. I have shot 60 rounds in an afternoon will no ill effects at all. The 500 NE is another good cartridge and still very easy to control and shoot but beyond that they start to get ridiculous and do not do anything better than the 470 or 500. They also get ridiculously heavy beyond the 500 by todays dangerous game rifle standards, who wants to lug around a 15 or 16 lb rifle for 2 shots when you can carry an 11 lb 458 Lott with 6 rounds in a Brno or CZ.
