For years it was the 270 with 130 Interlocks, that's all I had.
For the last 10 years or so I've been using more 100 gr Interlocks in the 257 Roberts and 250-3000. A few with the 87 Hot Core in a M99 250-3000. A couple with 95BT 243.
This year I got a doe with a home cast bullet in a 38-55.
They all work.
