Nice, I have a pre 64 model 70 fwt that shoots better than that:
Can I tape up 2 holes like you did and call it a 3 shot group?
My first rifle was a model 70. Still have it.
How much does one cost these days? I'll bet you could buy a Tikka and a decent scope for the same price.
As far as the tape, I'm frugal. I tape holes and use the targets again. They don't make those targets anymore. Different range day.
My math is a little shaky but I think my groups are smaller.
