WAIT A MINUTE..... I MUST HAVE JUST RODE IN ON THE TURNIP WAGON...
I measured some of my Fiocchi, Eley and Lapua bullets and they miked .224. I miked my "Offical" BR-50 scoring plug made by Bill Calfee for BR-50 and it miked .224 and I just tore up one of my RIG .22 cal scoring plugs and it miked .224. And now I read that a .224 diameter bullet will not make a .224 hole in paper, only a .204 hole..
Now, if that is the case, why in hell, if anyone can explain it to this totally ignorant shooter, do we use .224 scoring plugs to measure our targets for determing close scoring shots, if our bullets are only making .204 holes in the paper
And why would we subtract .204 from your groups, if the bullet diameter is .224.?? Maybe we are shooting these match .22's so fast that the bullet is actually melting in flight... OR, maybe the old thing about shoving a tomato in a catsup bottle has some credibility.. Give me a break..
If I shoot .224 diameter bullets in my rifle, for groups or score, I'm subtracting .224 from the edge-to-edge measurement of the farthest bullet holes. You measure yours anyway you want to..
