Mine was made by Jeffery. 25 inch barrel, no idea on the twist rate. I have taken a number of Cape Buffalo, 2 Hippo and a bunch of other plains game plus 2 Grizzlies, 3 Moose and a couple of Deer with it.

The original stock cracked last summer so a new one is being made with the exact same configuration. Just a couple of tweaks to fit me better.
