Hi Doubleriflejack,

Funny that the chopper lump subject came up. It just happens that in the last few days, I've been doing some research on the subject because I am planning on using them on the .700 that I am building now.

I know that it's a lot of work, but I want to be able to say that I made one.

Since forging the blanks is out of the question for me, I will use 1 1/2 x 2 1/2 bar stock, rough saw it and send it out for drilling and rifling.

I have some inquiries out for the drilling and rifling. I will post with the info when I get the answers.
