I sometimes get headaches when shooting harder kicking rifles. This is especially true if I have any sinus congestion when shooting. My M700 KS 338 WM is one of my favorite rifles, but it's a no go for me if I'm just a little congested. 1 shot and my head will start to throb, and really hurts by the 3rd shot. My 300 Weatherby and 375 H&H does the same.
One of the reasons my purchases in recent years have been smaller caliber rounds and none of the Uber magnums like a 300 RUM or 28 Nosler.
