I just got my bullet chart from Nosler in the mail today.Real nice.Approx 2x3 ft,color chart listing every bullet they make.The only .458 partition they make is the one you are using. 300gr protected point for 45/70.They do make a 250gr,but it is .429" partition-HG hollow point.If you want a chart,just email them,they are free for the asking.
