Re: 7mm Mag need load data
I haven't used the 140's in my 7mm mag, I shoot the 160 AB because of the better BC. I am using H1000 and federal 215's.
You would probably want a faster powder for the 140's. Try H4831sc if RL22 doesn't work out.
I am getting 3080 fps with the 160's in a 26" barrel. You should get 3100 maybe 3200 depending on barrel length.
