Daniel-
Thanks for the comment on the Jeffery.
What you see on the bolt is
most of a Jeffery patent peep sight, which I'm in the works of replacing a few missing parts.
Here's the patent application drawings of the sight.
As you can see in the drawing it's regulated for 100-500 yards. The reguation cam disc can be replaced too, which is a neat feature.
The replacement parts I'm making are true to the Jeffery design.
From what I've seen, it's a pretty rare feature.
I have a copy of the Jeffery factory ledger page confirming that this rifle was ordered and shipped with the patent sight, the banded 5-blade rear sight, and the proprietary Jeffery ivory-tipped and hooded front sight.
Here's the sight as advertised in a WJ Jeffery catalog from the period.
It's a cool rifle indeed.
On the topic of the carcano bullets I was using, they did not have a smaller seating diameter. They were .268 all the way from the base to the ogive, although I did turn the necks of the cases that I loaded with them to allow for clearance in the chamber throat.
So Daniel, let's see some photos of your rifle!
