Growing up in Ohio i got a lot of experience sighting in slug guns. So the shoulder pounding is not the problem. I can handle that part.

The problem for the last 10 years or so is the headache I get after shooting.

I am down to a 25-06 level now trying to avoid the painful concussion feeling. It actually feels like a force hits me in the head.

John barsness says his wife has the same issue and has gone to a 257 Roberts to help avoid it. That's my main rifle now and my 6.5x55 with a 129 at 2800 is still ok for now.
