I picked up 2 boxes of .358 250 grain round nose Herters bullets at a gunshow today. They are a very short round nose, only .050 longer than Speer 220 flat nose that I shoot out of my 350 rem mag. I think they will fit great in the short magazine of my 673. Any body have any load data for these bullets? Also, who made Herters bullets? And what can you tell me about them, when were they not produced anymore?
