I've had either 3 or 4 7mags can't exactly remember. The one I still own is M70 Custom Super Grade. With this one I had to go about 4.5 grains over a book max. load in order to reach 2900 fps with a 175 gr. bullet. I find its recoil to be more bothersome than a .338 win. mag I own altho admittedly the latter has a muzzle brake.

Today I use a 30-06 in place of the 7 mag even though the 7 is a far prettier gun.
