Interesting, I have a post '64 that I got for cheap, put on a Williams peep sight, and that thing really shoots at 100 yards. Since it isn't a pre 64, I carry it in my Kubota 900 where ever I go around my area, and not worrying about messing up a classic. 150 gr seems to work well and doesn't kick like a 170. Your pre 64 looks amazing and a great get, for sure.
