How is a 140 Interlock moving that slow going to perform on game?
I will find out. I used 277 caliber 140gr BTSP down to 1800fps with no issues and good expansion. Have also used 277 85gr TSX at 1900 fps with no expansion issues.
I could go with a softer bullet, like the SST but would have drop down in weight for length considerations for stabilization.
