I've started to drink the Kool-Aid on the Sinclair mandrel vs using an expander ball.
I do load on a Hornady LnL AP and generally use Hornady full length sizing dies with the expander ball. I'm under the impression that removing the expander ball in the full length die and adding the Sinclair mandrel after sizing will help with concentricity and SD's. I have however read various different threads where some use the expander mandrell and some use the turning neck mandrel. I know the turning neck is 0.02 under bullet diameter vs 0.01 for the expander.
I want to buy the carbide mandrels, as I assume I won't have to lube the inside of case mouths in that case. Am I right there? Do you think I'd be ok with going wtih the expander mandrel in carbide for the calibers I wish to load, or do you buy one of each the expander/turning and then measure different case brands to gauge spring back etc.... I'd prefer to get started and thought I'd just get the die and the expanders at first, and maybe add the turning if needed at a later date if I run into spring back issues on certain brands of brass etc... Sound ok?
P.S. Eager to start loading 6.5 Creedmoor and .224 Valkarie this week as dies and bullets are incoming.
