When the ballistic tips first came out I jumped on the bandwagon with everybody else.I loaded some for a .270 I used the 130 grain.The early ones were way to fragnable.Should have used the 140s.The later ones have been improved and stay together much better.I still use them in my 7s,But have long since went back to the Hornady interlock BTSP in most of my other calibers.That old bullet has been around for a long time and still does it's job reliably.JMHO
