Can't seem to find any data on CFE223 loads in the 7x57..Im thinking it would be a great powder??Anyone used it, if so what were your loads.

no experience, some QL with lower pressure and 20" barrel

Sierra 140 BTSP

Hodgdon CFE223
Fill Ratio - 82.7
Charge - 46.5
Vel - 2759
Prop.Burnt - 99.4
PSI - 49494


Sierra 140 SP 1910

Hodgdon CFE223
Fill Ratio - 77.6
Charge - 43.7
Vel. - 2540
Prop.Burnt - 97.5
PSI - 42000

think H-335 type powder Ray.

MR-3000 looks like a good one in the old war horse.
doubt there's any data around for it at anything approaching modern pressures though.
