I like the 6.5 inch 500 for bear country carry. I’m looking into the performance barrel shorter barrel or 3.5 comp Model. Are there any weight or bullet types that key hold or otherwise don’t run right? My 10mm doesn’t like anything above 200 grain so that’s why I ask. I also have heard of bullets jumping the crimp with the 340pd. I don’t want to risk keyholing, or cylinder lock up on a bear gun. Has anyone gone expansion or max penetration tests with different billets for a 500? I would like to load my first two with expanding and my last 3 with the deepest penetrating I can find.
