My objection to the belted case is that chambers do not seem to be held to as close tolerances as for non-belted cartridges. As a result there is more stretching and the cases do not last as long. The become thinned just above the belt, and separate if not checked regularly.
I found this in both the 7MM Rem Mag, and 300 Wby Mag.
Of course if you do not reload you do not experience this problem.
Ecclesiastes 12:13 *¶Let us hear the conclusion of the whole matter: Fear God, and keep his commandments: for this is the whole duty of man.
14 *For God shall bring every work into judgment, with every secret thing, whether it be good, or whether it be evil.
