Anyone whom doesn't see a difference in the quality bullets made of late an the original 1950s fodder doesn't understand the bonding process. Not knowing why the jacket seperated from the lead after it hit a rib on a deer size animal, content to think ,"it killed the deer/elk so it must be good". A theroy that runs quickly a muck when the shooter tries to use that same caliber/ammo combo on tougher game.
FTR there was a time the .270 was considered the top of the chain for elk and all the gun scribes such as O'connor,Barness,etc. wrote glowing reports on it. To me if Ineedto use bullets to make my 270 an '06 I'd rather just buy an '06 to begin with.
