why not rent one? its about $50 to rent it.
I rented a .404 Jeff reamer a couple years ago and then discovered that someone would have sold me theirs for the same price as I rented.
I'd prefer to buy one from someone because I can do me and the seller a favor.....I'm assuming there is very little call for .30-30 reamers.....and frankly, I'm not totally sure this will be my last double rifle attempt in .30-30. I have another sesquita waiting for some fun project as well.
