The first deer I shot with my .270, I was shooting the Remington 150gr shells and the deer acted as if it wasn't even hit. A second round put it down and a third round at close range put it away. Upon skinning the deer and looking at the damage, it was obvious that the bullet didn't expand much if any at all. The deer had what looked like a small puncture wound where thre bullet entered and a slightly larger wound on the exit. I explained to a fellow that was shooting his .270 what had happend and he imediately told me to go to a 130 grain. I did and the following season and most seasons afterwards it's been 1 shot ,1 kill with no tracking involved. I'm sold on the 130 grain loads and it don't matter much whether it's a Remingtom, Federal or Winchester shell just as long as it's a 130 grain and you put it through the boiler room.
