Cast bullets with and without a gas check

YOU TRY THEM

is changed. Where typically the base of a bullet as it leaves the barrel rifling crown emits gas evenly and smoothly to ensure the bullet continues to fly true. When the crown is boogered this even flow is disrupted and the bullet base can be tripped up some. Sort of like what me throwing a football looks like. I never could get that "spiral" throw figured out.

Not using a check on a gas check bullet de-facto moves the bullet "base" up to the bottom driving band. That is "now" the base where gas has to smoothly escape as the bullet exits the bore. Sometimes it does and then maybe not. Depends on the bullet design and how it manages this. Teeny grooves like like some of the LEE designs might not work so good then an old heavy banded Keith or Thompson design might shoot as well as no gas check. Then one more factor, the bore, might iron all things out and force it to work fine.

*You should see my bow shooting arrow's release too, that would be a good analogy! Wobble ass.

In my experience and limited ability, at short range, I can't really tell the difference with a .38 wheelgun. It sometimes seems a waste of checks doesn't it?!
