I used to, and still do shoot this load in my 458 winnie. It is 67 gr H4198 under a hornady 300 gr. hp with rem brass and a cci 200 primer. My notes are gone, probably to the place where single socks go. I was wondering if someone could give an approximate fps on this out of a 21" bbl. It shoots a 1" group at 100 but I can't find the rest of the numbers. Thanks.

Mick,
Thank you so much for the info! It is almost exact to what the chrono said. I feel much better now about the pressures! You'll get good karma points for this one!

I’m glad it helped.
