Well , SR I cannot speak for KK , but I believe what he is saying is that many reknowned lighter calibers , .222 . 223 , .243 & 25-06 pushing 50 , 60 70 or 130 grain Sirocco's conventionally used for open country medium game hunting are much more likely to be diverted from their intended path traveling at 2880 - 3380 fps . Than any 30 , 32 or .45×70 caliber nozler partition or Aframe rounds of 180 , 200 , 220 , 325 or 405 grains traveling at 1350 to 1895 fps . I however , was originally speaking specifically of my Marlin 450 Big bore pushing a much heavier & blunted 500 grain projectile , which is very stable in flight . No I never intentionally bush bust any more than I would sound shoot. I hunt ethically and load the best loads & rifle to the application brother . Anyhow good discussions , think we should give the thread back to the wood cutting fella's .. Cheers Gentlemen !
