Yes, you are correct, an old experienced hunter made a remark regarding the calibers hunters are using ....to him it seems the animals has evolved into targets with very thick skin and bones and are extremely difficult to kill... hence the muzzle velocity off calibers are increasing at a rapid pace , only felt recoil put a damper on the velocity increase needed to kill animals...maybe it is a good thing since the next re- cambering will be a Lott 458 ...that will remove any teeth fillings I have...I am prone to head-aches......
