The point is that with a longer case and 19% more powder space, an extra .1" in bullet length isn't going to handicap a .30-06 the way you think it does a .308 Win.
* * * * The "handicap" from a longer bullet is about the same in either case since the bullets are the same diameter, and thus the loss of powder space is exactly the same. * * * *
Mr. L Bob - I can't find the thread or I'd quote our own Mule Deer (J B). He has said more than once that "seating bullets deeper does NOT take up powder space".
There is such a thing as 'compressed' charges. Yes, there is a limit as to how much we can compress a charge. Using slow burning powders I have used several 'compressed' powder charges. I have, and still use 1 load which does, seated bullets in cases where there is NO MORE room for powder.
Some have reported having bullets pushed back out 'some' from excessive compression. What you are talking about > .1 length < is a non issue.
