I recently picked up this interesting rolling block rifle. It is chambered in 10.25x69R Hunting Express. Is kind of beefy, weighing 7.5 lbs with a 25 5/8" octagonal barrel. Rifling is of the fast express kind. Most of my rolling blocks have a slow twist. It has a rear sight similar to ones on some Swiss rifles of the era I have seen.

It is my understanding that the 10.25x69R was developed for rifles for the Africa trade. I assume by that they mean for hunters of African game in the late 19th century. Seems to be a reasonably potent cartridge. What kinds of game would this rifle have been suited to?
