Here is a " Pet Load " that I'll share.
I had 4 in a ' ragged hole ' and you guessed it,
...............the 5th one flew slightly high and
left out of the group.
A super accurate load out of my 358 Win.
You can easily see that the gas check shank
protrudes down past the end of the case neck.
Many say this is a " No - No ", I can't tell that
it has any effect on my accuracy.
