Redneck: My experience with the .300 H&H brass coincides with yours. I neck size minimally and bolt closes with very slight resistance. After a number of firings, a full-length size may be required. I've never counted the number of times a case can be loaded, but it's comparable with other rifle brass.
Exactly.
Just guessing, but I'd say full-length sizing after each firing would limit case life to four or five loadings, particularly if a stout load is used.
You're not guessing my friend - you're spot on. Full-length sizing for a belted magnum is honestly safe to 3.. I would not go over 4 before tossing and starting over.. But that's just me.
