Nosler brass CA ridgeline 175 EH
Retumbo 62 gr got me 2911
N560 60.6 gr got 2917 fps
Retumbo load at 60, 61, 62 gr of retumbo were all touching so that was my first real trial handload after breaking in. Might have just hot the easy button. Not sure i need to push for more than 2911 fps with a 175gr. Bolt lift was easy on all.

I would keep it there.
