Thread: Why do .22s have such different accuracy with different ammunition?

Back to the original question of why .22 ammunition type is so vital to precision. To put it simply, its the ratio of powder dispensing error vs case size.

If say all bulk ammunition machines accidentally introduce a + or - .1gn error. In a 50 cal case thats .01% of the over all charge in every case. But the same margin of error in the .22 machine.... that makes a 5% margin of error. In short, .22 is a bitch to keep consistant. Any reloader will tell you that not all kernels of powder weigh the same (some have more /less carbon). Humidity would also effect on .22 ammo. Then there's the priming agent... even more variation. Im surprised anyone gets accuracy out of this cal really.
