I want to say it was based on a .30-40 krag case with the rim turned down to fit a 30-30 bolt. It is a case I have wanted to get to down the road, the 30-40 case that is. My end goals with this rifle are a simple rifle with a peep sight, 22-24" barrel and decent ballistics that will take a deer cleanly out to around 200 yards. I will have to check in to that leverpower tho. Thanks for the new idea
