I inherited one of my grandpa's Biesen rifles. It is built on an FN Mauser. It is a 7x57 with a 22" barrel. It still has the 4x Redfield my grandpa put on it. It was built in the late 60s. I think I remember my grandpa telling me that it was O connor's writing that got him thinking about Biesen.
The only thing I've changed is I installed a Tom Burgess safety that I got from D'Arcy.
I've killed a few cow elk, a black bear, and some antelope bucks with it.
My mom can remember her folks loading up the family and driving over the mtn to visit Biesen. I never did get to meet him.
I should get some better pictures of it. It has a trap door buttplate and a skeleton grip cap.
I still have untouched brass from my grandpa's stash.
