I noticed on my '32 Izzy that the bolhas a fair bit of drag as if it were a littl scarred up from use. Would it be safe to polish the bolt body? I have heard of people doing it but never attempted it myself.
totally safe to do. I have over 90 Mosins and have polished quite a few of the ones that I have gotten around to using so far. Just be careful not to take too much off. If that doesn't work then pm me and I can put you in touch with a few hundred spare bolts and other parts that you might need.
