This was my VERY expensive Ballard (WY) High Wall filled with special order features. It was a 300 H&H. Did not work as the extraction system was 1885 High Wall. Had it converted to 30 Super Flanged. Would now work with loads at 30-40 Krag levels. Sold it to a fellow who was going to rebore it to 45-70 BP cast bullets. Worked fine.

Ballards, now made in MI, are not the rifles the WY guns were.

Consider yourself "advised" by one who has been down that road.

IMHO the best single shot to convert to a thumper is the older Ruger No. 1 "red pads".

450 3&1/2" NE. (serious pad added no cutting)
