I just picked up an older 80s vintage 457193. The owner claimed it was a 500 grain. I looked in an old cast bullet manual and see it listed as 420 grains but I also know that to be the 405 grain RNFP that is offered to this day.
Did they change the nominal weight of this at some point? I have not cast with it yet so I’m not sure on the actual weight.
Thanks!
