I thought I would chime in.Picked up a 3/8 grade 8 bolt on the way home from work.
Finally located my punch set.
Converted the bolt to cock on close, but I have more to do here as the closing force is too high.
Waiting for the scope to arrive. Waiting to pick up weaver bases and modify them.
Nice to see you starting this project.
I will gladly help if necessary.
