My next project will be to chronograph these loads. It's my understanding that the original .310 ballistics called for a 120 grain bullet at ~1,200 fps. I want to duplicate the original ballistics as near as possible so the rifle will shoot to the sights at longer ranges. I hope to have it perform at 200 and 300 yards. It will be a rainbow trajectory for sure.

It will be a couple of weeks before I can do this, but I will report back. Stay tuned.
