I have used the Hornady Light magnums and the Interbond bullets when reloading in 130gn 270.
The light magnums do what they say on the box, I did a review on them for a mag’ a few years ago, I will see if I can find a copy of it. But they grouped around .75 moa in my rifle and were doing 3100 fps from a 22” barrel.
The projectiles worked fine on UK deer, red/Sika but I found that they did not give any better results than SST but cost a lot more money.
If I was shooting animals bigger than UK deer then I would look again at either Light Magnums or Interbond heads. I found the 270 has enough power with “normal” deer loads for the UK.
