nice debate annd got me wondering so i broke out the bible(graeme wright book#2)and see what he thought.seems he included even modern steel core bullets regaurdless of how much lead in it as the same as mono metal bullets,he quoated that no hard are reccomended in H+H rifles period.he did a test with a kynoch person and they milled a barrel down and with the use of hydrolics pushed the projectile through the tube and miced it soft points showed no barrel expansion then a hard bullet it showed .0005 surge then it returned to prior measurement.so classed as hard were partition,solid copper or brass or bronze or steel in the core.he states there is no reason to shoot a hard bullet out of a double.reasonable to assume few of us will hunt elephant if so not many times.and do buffalo need solids will softs do a lethal amount of damage.even though i am a die hard barnes fan and will still use them in my bolt guns i will only shoot regular soft points out of my doubles my mind has been changed.to me that initial expansion could do something to the joining system of any double.but not only solids but all HARD bullets.will be intersested to dee if he addresses the x bullet in volume three.but again that was with a shaved barrel i wonder what a regular barrel would mic out to with the same test.so many variables,so many views no wonder this has been debated so long.thanks ripp nice group debate.
