7mm mag and IMR 7977

[CWEAGLES]

Has anyone worked up a load for 7mm mag using imr 7977 and 150 g xld

Worked on a load woth 150 gr Nosler BT and 7977. Load seemed to be very good and consistent. Better than H4831 that I had traditionally used. best results with a bit less than book max.

Not in a 7 Remmag but tried in a 300winmag and while the velocity was good, it did not match the accuracy of H-4831.

Every rifle is different. Good luck.
