Can you give us a little more info?
What year? What type of stock? What type of barrel, thin or thick?
7mm is one hell of a great round. I have one on my long range tactical and I love the performance. It's impressive and it hits like a run away truck.
For the record, the pre' 64 model 70 is THE Rifleman's action. It's what Carlos used, in .30-06, in Vietnam to create all that havoc.
