Seems like if you're gonna make a 1900 era sporter, you probably don't need a military style bent bolt, but maybe a Mannlicher style "butter knife" handle would be better for the period.I did some research, and from what I can tell (my research has in no way been exhaustive), the early John Rigby sporters had regular bolts. He was already building sporters out of them in 1898, and the one I've been specifically looking at is a small ring 98, like the Kar 98. It was a small ring action that took a large ring barrel. Another interesting thing about that rifle is that it had the military pattern sights and a stepped barrel. From what the site says, Rigby bought barreled actions from Mauser and then built sporters out of them. The one I'm using is actually a Husqvarna and has set triggers.
