Whyat Ocumpaugh sells 35 cal rebores on GB that his brother does ( http://www.35caliber.com/ ).

Here's one of his 760/35 Whelen rebores: http://www.gunbroker.com/Auction/ViewItem.aspx?Item=264618067

My brother bought a Mauser 30-06 from him that had been rebored to 35 Whelen, and it shoots VERY well.
