I have a Model 64 in 32 WS my father passed down to me. His was 1956. The 64 was only slightly different in it had a longer barrel, 3/4 length tube mag and a pistol grip. The action was the same.
I have never handloaded for it but I know it shoots very well with factory 170 gr. Silvertip. I have shot a few deer with it, a few elk and some coyotes.
There are very limited numbers of available factory ammo and very few component bullets for the 32 WS.
