A blued Knight DISC Elite or similar in .45 w/a rifling twist appropriate for a 200gr SW. Here is the real challenge: An actual walnut stock! Not laminated or anything else. Actual walnut with cut checkering.
Basically make an affordable inline that looks and handles like a good bolt-action centerfire and is capable of 200 yard accuracy.
My .50 DISC Elite is about perfect for me. Just kind of ugly.
