An update as promised.
Shooting the Winchester 70 classic featherweight today.
Lapua brass, Federal 210 match primers, and reloader 26 under the 140 grain partition.
3 shot groups, velocity recorded is the average for the three shots according to my lab radar.
50.0: 2808 fps
50.5: 2849 fps
51.0: 2877 fps
Based on the velocity of the 51.0 load I did not shoot the 51.5 or the 52.0 loads I had with me.
Those are good numbers. Much better than what I saw out of my M70 FWT with 140 NPs with RL 22.
Thanks for sharing.
