This is all good advice. I will have most of the metal work done by 'smith drill & tap, new bolt handle. I could take care of stock, new safety, trigger. Have re-blue done by smith. A couple years ago I acquired an 1891 that had a scope mounted, got a buehler safety and glass bedded it in the original military stock that was cut down. Handloads put two in the same hole @ 50 yards. About an inch at 100 yards. That's in 7.65 x 53. This one goes out in the woods with me sometimes and has taken a few deer so far. One shot was all that was needed. 150 grain Spitzer.
I think I need to go slow with this latest Argentine. I'll swap out an expander nipple for .31 cal. and load up some starting loads for the .31-'06. If it looks promising I'll go get new laminated stock, glass bed action AND I'll look for trigger/safety. Leave issue sights alone & bolt, just get her a re-blue. Maybe better to look for an 8mm/06 already put together?
