I shot 3 gun matches for 20 years. In that time I had only one kaboom it was from faulty, locally re-manufactured 5.56mm NATO ammo using Lake City brass. When the case ruptured it blew a hole out the side of the case just in front of the rim. It also blew the magazine out of the lower & cracked the bolt carrier. The bolt itself appears to be still functional but I retired it anyway. No telling if there are invisible cracks in the lugs. No injuries to me! 
I have headspace gauges for all the gas guns I shoot - 6.5 Grendel, 6mm ARC, 7.62X40WT, M1A & M1 Garand. I also have headspace gauges for some of my bolt guns that are used rifles - 8mm Mauser, 7.7 Jap (NO-GO would chamber in this rifle) & 7.62x54R. I use the M1A & M1 Garand gauges with my .308 Win Spanish Mauser (also excessive headspace), Springfield 1903A3 & J.C. Higgins Model 50 30-06 as well.

I refuse to be victimized by notions of virtuous behavior.
