Back in the early 1970's when I had several .303's and lived in Indiana, I was thinking about re-chambering my cut-down Pattern 14 to the Epps improved .303. One Saturday a friend and I drove over to Ontario and spent a couple of hours at the Ellwood Epps store. We met Ellwood who did not have a lot to say. We mostly talked with an Austrian born gunsmith who was working for him.
The Pattern 14 had a bore that was not worth converting. I ended up rebarreling it to .30/40 Krag and then selling the barreled action when I realized how much the stock would cost.
