Long range hunting, the lower end of big game hunting.
NO!!
100-500 or so
NO, doubt it would even seat completely in. The base of the 7mm magnum (case before neck) is longer then a 30-06.
Sako, and Remington are two different manufacturers.
Define 7mm. Do you mean 7mm Mauser ( a little less than 30-06), or 7mm Magnum, (a bit more than 30-06)
The 7mm Remingtonn is longer. The 30/06 has a larger projectile.
Browning did not make the Model 70, Winchester did. Also, the serial number is not a valid Browning serial number for a 7mm Magnum rifle. Please doublecheck your information.
No specific records. The 7mm Magnum is not a military round, nor is it specifically used in long range competition.
Only 7mm magnum ammo made by a reputable ammunition maker provided the rifle is in working order.
You may use any brand of 7mm Magnum rifle ammo.
AFAIK, no one has tried to make an AR upper in 7mm Magnum
If 7mm Magnum, it trumps the others.
