6.5CM small or large primers?

[Waco]

What is the advantage if any in using small rifle primers over large rifle primers in the 6.5 Creedmoore?
Those of you using small rifle, are you using std or mag primers?
Thanks.

From what I’ve gathered the small primer leaves more brass in the case head and so it can withstand a little higher pressures. Now my question is will it allow you enough pressure leeway to get to the next node up or are you going to be at the same velocity node anyways thus making the extra money for the small primer a lost investment? Or will the extra meat in the case allow you three to four more firings, that could be worth it. Those are just points I’m curious about as well.

For a creed I would go mag if you’re going to go small primer, if large just regular I should imagine.
