That is going to be a tough one, not enough demand for barrel makers to tool up for the job.

You spoke to Krieger? Offered to pay for tooling? John would take on special projects in the past if he found it interesting.

Short cut? Have your reamer reground or another made to shoot .284" bullets.

The odd British bore sizes present a real challenge today, I have a .475 #2 Jeffery and have recently sold a couple of Holland .240 rifles.
