That load will get a stiff bolt with 140's in my rifle. I use 68 with 150's in mine at around 3100 fps.70.5 gr IMR 7828 160 game king was the most accurate in my Ruger #1
I'm using 56 I 4064 with a 140 sierra and a mag cci for 3050 fps chrono'd.
I've used rl22 at the 68 grain range with 140's and it was good. I've seen 68-70 grain max's depending on bullet with it. The last rifle did 3200 with it, I'd expect similar for this one, but I really don't care as it is a paper puncher for me.
