Pretty sure that grinding technique was only done on guns that were for the Cabellas contract as they had a deadline time wise they couldn't meet. I saw a youtube clip once where the MD from memory was explaining what happened and appologising. Pretty sure too that the guns in question were more US orientated so 30-06 and 45-70. Our US friends can chime in if they know of more.
So it's unlikely that you would come across one of the Dremel guns here in Australia.
