I find the 130gr has a better drop table than the 140gr which is better than the 150gr within the efective range of a .270win..But the 140gr will penetrate better with less chance of bullet failure than the 130gr but expand better and distribute more energy in the wound channel than the 150gr.Your old Rem.corelokt were famous for bullet failure if they hit bone but great if the shot was right.The cause was the oxidization that develloped between the jacket and core when the hot core was inserted.The new bonded core and stretched ogive has eleminated this problem.It is just personal but I believe some of the other bonded bullets are better.But if you like corelokt,use them.I only have the bullet failure against them.You cant buy the new Rem.bonded corelokt bullets to reload,only loaded ammo. Plus,I have had Rem.factory loads fail to fire period.Only on the range thank GOD.You can use a ,270 on very little game in africa and only if backed up with a big bore. samYour not going to go wrong with a .270 in any choice. The 140 is only better if you need longer range. This gun has stopped everything here and in Africa also.
NewTx, where were you hunting? We've got a lot of nice deer around here but it's been so warm that we haven't seen squat where I'm at.Samuel has a point I did not consider. Not that my experience is deep or based on years of experience. The deer I shot outside Abilene last weekend was not clean through the deer. I shot in the lower neck (slightly facing me) and it exited the shoulder... but did not exit. I actually found the bullet lodged under the skin on the exit side with a bunch of bone. Sorry for being graphic but I may consider the 140gr.
i use the 150 gr. in the fedral ammunition. what do you think of those?Use these in 150gr for the .270: Cabela's -- Winchester XP3 Supreme Elite Rifle Ammunition
Should take down an elk with ease.
