Re-read J. D. Steele's post again and pay particular attention to the part about checking for excessive headspace. I once had that situation occur with an M-98 VZ24 rebarreled to .22-250. On the third shot with a fairly mild load several grains below max, I had a complete head seperation and was totally blind for about 20-30 minutes and had very blurry vision for some time after. Trust me, a lot goes through your mind when you are blinded. Paul Mausers' improved bold shroud on the M-98 which helped deflect gas from the shooters eye is probably the only reason I can see to write this. Safety glasses became standard equipment in my range box.
